Checkmarx sells enterprise application security, scanning source code, open-source dependencies, APIs and running applications for banks, hospitals and governments. In 2026 attackers turned its own developer tools against the developers who install them, publishing poisoned Checkmarx container images, editor extensions and build workflows from its repositories. Checkmarx confirmed that data was taken from its GitHub environment, and the investigation it completed with Mandiant found no attacker access to the Checkmarx One service. The platform business kept moving through all of it. Autonomous remediation agents reached general availability in July with a named healthcare customer describing the result, and the government edition holds a FedRAMP Moderate certification.

How well the company can compete in its security market, scored across eight dimensions against public evidence.
| Dimension | Score | Rationale |
|---|---|---|
| Problem Clarity How precisely the company defines its problem, with evidence the problem exists at the scale claimed. | 4/5 | Checkmarx names the enterprise application-security team that owns the code its developers ship, and the pain behind that is sized outside the vendor's own pages. A Register article describes a 2026 campaign that poisoned trusted developer security tools, one of them a command-line tool from a password manager more than 10 million people use, and the EU Cyber Resilience Act requires manufacturers to report actively exploited vulnerabilities from 11 September 2026. [s8, s20, s24, s22] |
| Capability Depth How specific the technical capabilities are, with evidence beyond marketing claims such as docs and third-party validation. | 4/5 | Product pages document static, dependency, API, container, infrastructure-as-code and dynamic scanning under one correlation layer, and outside parties have covered the code itself. A BleepingComputer article describes KICS, the open-source infrastructure-as-code scanner Checkmarx distributes, down to its clean replacement versions, and Forrester evaluated Checkmarx static analysis alongside nine other vendors. No independent evaluation of the newer AI-assisted scanning appears in the reviewed sources. [s4, s5, s7, s20, s21, s22] |
| Market Timing Whether the market is ready for this product, with evidence that buyers are actively seeking solutions. | 4/5 | Two demand signals are recent, one regulatory and one from analyst research. The EU Cyber Resilience Act requires manufacturers to report actively exploited vulnerabilities within 24 hours from 11 September 2026, a regulatory driver, and Forrester's 2025 static-analysis buyer's guide reports that buyers assess about three vendors before choosing and keep the product about four years. Checkmarx separately announced a placement in Gartner's first Magic Quadrant for software supply chain security, dated June 2026. [s24, s22, s16] |
| Team Credibility Demonstrated domain expertise with public signals such as prior exits, publications, and industry recognition. | 4/5 | Chief executive Sandeep Johri founded and sold Oblix to Oracle and Determina and Bluelane to VMware, then ran Tricentis for seven years, and a March 2023 ChannelPro article records his appointment. Co-founder Maty Siman has run technology since the 2006 founding. Checkmarx states those prior exits on its about page, and a March 2023 ChannelPro article records the CEO transition it describes. [s8, s25, s26, s28] |
| GTM Proof Evidence of actual traction (customers, revenue signals, partnerships) beyond stated intentions. | 4/5 | Carahsoft resells the platform to public-sector buyers through NASA SEWP V, the E&I Cooperative Services Contract and The Quilt, a verifiable route into public-sector budgets, and a March 2023 ChannelPro article records more than 1,800 customers. The analyst leader placements and the company's own revenue and customer figures reach the record through Checkmarx itself, so the scale claims carry no current independent check. [s15, s25, s8, s16] |
| Funding Efficiency Whether funding matches go-to-market ambition, with signs of capital-efficient growth. | 3/5 | Hellman and Friedman bought Checkmarx from Insight Partners in 2020 for 1.15 billion dollars, and the output since is visible in a consolidated platform, the Tromzo acquisition and a steady release cadence through 2026. Checkmarx states on its own about page that Checkmarx One passed 150 million dollars in annual recurring revenue within three years. No independent source confirms that figure and margins stay private, so output per dollar deployed is not confirmed. [s28, s8, s26, s14] |
| Category Clarity Whether the company creates or fits a recognizable category that buyers can quickly place in their stack. | 4/5 | Application security testing, application security posture management and software supply chain security are all named analyst categories, and Forrester's static-analysis review lists Checkmarx among the ten vendors it evaluated, so a buyer can place the platform without vendor coaching. The specific leader placements reach the public record through Checkmarx announcements rather than independent distribution. [s22, s16, s8, s5] |
| Incumbent Defensibility How vulnerable the core value proposition is to absorption as a feature by a platform vendor. | 4/5 | Checkmarx holds a position bundling alone would not reproduce. It carries a FedRAMP Moderate certification for its government edition, a federal reseller route through Carahsoft, and a curated malicious-package corpus the platform scores dependencies against. Forrester's finding that the barrier to entering static analysis has never been lower is the pressure on the other side. [s23, s15, s11, s22] |
Checkmarx sells to the enterprise security and application-security team that owns the code its developers ship, and it frames the problem as securing that code from creation through runtime. The homepage describes helping teams prevent, prioritize, remediate and govern risk across what it calls the AI-driven software development lifecycle. The about page puts the same idea plainly, saying Checkmarx protects the software that powers banks, hospitals, governments and the products millions of people use.
Outside evidence sizes that problem rather than leaving it vendor-asserted. A Register article describes a 2026 campaign in which attackers poisoned open-source security tools to steal developer credentials, reaching the command-line tool of Bitwarden, a password manager more than 10 million people and 50,000 businesses use. Regulation is moving on the same ground. From 11 September 2026 the EU Cyber Resilience Act requires manufacturers of products with digital elements to report actively exploited vulnerabilities within 24 hours.
A newer segment is the team adopting AI coding assistants. Forrester reports that wider adoption of AI coding assistants and agents increases the amount of code that has to be secure before deployment, and Checkmarx sells Developer Assist into that gap, running inside editors such as Cursor, Windsurf and VS Code alongside the assistants writing the code. [s1, s8, s20, s24, s22, s9]
Checkmarx One pairs proprietary scanners with a correlation layer rather than only aggregating other tools. It runs static analysis on a hybrid engine and dependency analysis with exploitable-path reachability, which determines which vulnerable third-party functions an application may call at runtime. Infrastructure-as-code, secrets, container and dynamic testing run beside them, and an API engine reads source code and documentation to find the undocumented, shadow and zombie endpoints that gateways and firewalls miss.
The platform prioritizes rather than only detecting. Checkmarx One ASPM blends exploitability, reachability, fixability and runtime exposure into one risk score, and it consumes SARIF results so a team can bring findings from other tools into the same view. Checkmarx says the platform integrates across more than 75 languages and 100 frameworks.
The agent layer moved from announcement to general availability in July 2026. Developer Assist runs a find-and-fix loop inside the editor, and the Triage and Remediation agents separate exploitable risk from severity noise and open merge-ready pull requests that developers review before merging. Checkmarx Fusion is the newest and least examined piece, running a curated set of validated large-language models beside the rules-based scanner, and the reviewed sources carry no independent evaluation of its accuracy. [s3, s4, s5, s6, s7, s9, s13, s14]
Checkmarx competes as an incumbent in a market Forrester now calls mature. Forrester's 2025 static-analysis review evaluated Checkmarx alongside Black Duck, GitHub, GitLab, HCLSoftware, Mend.io, OpenText, Snyk, Sonar and Veracode, and reported that competition has intensified and differentiation has become harder as the core technology settled and consolidation spread.
Pressure comes from below as well as from the platforms. Forrester notes that the barrier to entering static analysis has never been lower, because a new vendor can build a working static-analysis product on large language models and free open-source scanners. Checkmarx answers with breadth rather than the scanner alone, and its own comparison page argues that lightweight open-source static analysis leaves gaps a consolidated platform closes.
Checkmarx also carries an exposure in its own supply chain. A Register article states the same 2026 campaign compromised Trivy, LiteLLM and the Bitwarden command-line tool, so Checkmarx is one of several security vendors caught in it. For a company whose platform is sold to stop that attack, the incident is what a security review raises at the outset. [s22, s29, s20, s1]
Checkmarx has enterprise traction, and most of the numbers behind it come from Checkmarx. A March 2023 ChannelPro article states the company served more than 1,800 customers, the most recent count from an outside source in the reviewed record. The about page adds its own figures, saying nine analyst firms rate Checkmarx a leader and that Checkmarx One passed 150 million dollars in annual recurring revenue within three years.
Checkmarx opened a federal channel in June 2026. Carahsoft became Checkmarx's Master Government Aggregator in June 2026, selling the platform through NASA SEWP V, the E&I Cooperative Services Contract and The Quilt, which are contract vehicles agencies buy through. Checkmarx One for Government has held a FedRAMP Moderate certification since 12 June 2026.
The agent business has one named account rather than none. PatientPoint's application security engineer described the Triage and Remediation agents identifying false positives and letting developers review before merging, the one customer voice on the AI layer in the reviewed record. The reviewed sources carry no adoption figure for that layer, and no independent benchmark of it appears in the reviewed sources. [s25, s8, s15, s23, s14]
Checkmarx pairs a founder who built the company with a chief executive who has sold security companies before. Maty Siman has overseen technology as founder since 2006. Co-founder Emmanuel Benzaquen led the company for 17 years and stayed on the board after the 2023 transition a March 2023 ChannelPro article records.
Sandeep Johri founded and sold Oblix to Oracle and Determina and Bluelane to VMware, then ran Tricentis for seven years and earlier grew HP's software division. Checkmarx states those prior exits on its own about page, and a March 2023 ChannelPro article records the appointment.
The AI bench came partly by acquisition. A SecurityWeek roundup states that the December 2025 Tromzo deal brought a team specializing in autonomous security agents into the product and engineering organization, Checkmarx said in December 2025 that the Tromzo reasoning engine would power new Assist agents from early 2026, and the Assist agents reached general availability in July 2026. Checkmarx says its own research team has disclosed hundreds of vulnerabilities in open-source packages, AI models and cloud infrastructure, a claim the reviewed sources do not independently corroborate. [s8, s25, s26, s14, s28, s17]
Checkmarx documents the assurance program an enterprise code-security buyer checks. The trust center lists ISO/IEC 27001:2022 certification, an annual independent SOC 2 Type II audit available on request, and alignment with the NIST Secure Software Development Framework. Checkmarx One for Government holds a separate FedRAMP Moderate certification, certified since 12 June 2026, a federal authorization recorded on the government's own marketplace.
What the products read matters as much as the certificates. Checkmarx One analyzes source code, dependencies, secrets and pipeline configuration for the customers who connect it, while the Developer Assist page states that source code stays on the developer's machine and only minimal metadata leaves it, so a security review can treat the editor agent and the platform separately.
The readiness item a buyer raises first is Checkmarx's own 2026 compromise. Attackers reached its GitHub repositories through the Trivy supply chain attack and published malicious code in externally distributed artifacts including VS Code extensions, GitHub Actions workflows and a Jenkins plugin, and a BleepingComputer article lists the clean replacement versions. A SecurityWeek article states the attackers exfiltrated data from that environment on 30 March, and the investigation Checkmarx completed with Mandiant reported no attacker access to the Checkmarx One service. The National Vulnerability Database separately records CVE-2023-35142, a flaw in the Jenkins Checkmarx Plugin that disabled TLS validation by default. [s12, s23, s9, s18, s21, s19, s27]

press the advantage
Checkmarx sells software its customers configure and run, so durability comes from what a team wires it into and who signs the purchase order. The asset Checkmarx accumulates rather than buys is a curated list of bad software. It describes a database of more than 420,000 human-verified malicious packages across 92.8 million versions, built by its own research team and sold separately through an API. A funded rival scanning the same public registries could build comparable coverage with time and effort. What raises the cost of leaving is narrower than the breadth of the platform suggests. Policy gates wired into editors and build pipelines, a regulated and government customer base, and a FedRAMP Moderate certification for the government edition are what a replacement has to reproduce.
| Dimension | Score | Rationale |
|---|---|---|
| Value Delivery Does the product sell software as the product, or judgment, trust, or accountability with software as the delivery mechanism. | 1/3 | Customers buy scanning and correlation software their own teams configure, run and act on. The risk scoring, the validated fixes Developer Assist applies in the editor, and the merge-ready pull requests the Remediation agent opens are automated output of that software, with the customer's developers reviewing and merging every change. |
| Switching Cost How expensive leaving is for a customer: data portability, integrations, learned workflows, network effects, regulatory data residency. | 2/3 | Leaving means re-establishing scanning and policy gates across editors and build pipelines and rebuilding the remediation history the platform tracks across every repository, which is integration and workflow friction rather than a rebuild only Checkmarx can supply. Forrester reports buyers keep a chosen static-analysis product about 4.1 years, which measures tenure rather than exit cost, and the cited record does not size the migration. |
| Compliance Moat Whether certifications, liability acceptance, or audit trails block an easy replacement. | 2/3 | Checkmarx One for Government is listed FedRAMP Certified at the Moderate baseline, certified since 12 June 2026, a government review a replacement has to obtain in its own right before a federal buyer can substitute it. ISO/IEC 27001:2022 certification and an annual SOC 2 Type II audit sit beneath it as the commercial baseline a funded competitor can obtain. |
| Problem Complexity Whether the product requires ML, optimization, real-time systems, or years of specialized expertise. | 3/3 | Static analysis, dependency reachability that determines which vulnerable library functions an application may call at runtime, source-level discovery of undocumented APIs, and machine-learning models Checkmarx says it trains to detect novel vulnerability classes are program-analysis work that takes years of specialized expertise. |
| Buyer Profile Whether buyers are SMB operators, mid-market IT teams, or regulated enterprises and governments with procurement gates. | 3/3 | The buyers are regulated enterprises and governments. Checkmarx One for Government holds a federal authorization, Carahsoft resells the platform through federal contract vehicles, and the customer speaking publicly about the remediation agents is a healthcare technology company whose stated priority is protecting patient data. |
| Layer Whether the product is an end-user application, a platform with application features, or infrastructure other applications depend on. | 2/3 | Checkmarx One is a platform that other tools feed rather than infrastructure other applications run on. It ingests SARIF results from third-party scanners and correlates them with its own findings, and its agents act inside the editors and pipelines a customer already operates. |
| Proprietary Data, Content, or IP Whether the product accumulates datasets, content licenses, or IP that a rival cannot recreate from scratch. | 2/3 | Checkmarx retains a curated corpus rather than only ingesting public feeds. It describes a database of more than 420,000 human-verified malicious packages across 92.8 million versions, expanded by its own research team from behavioural analysis, community feeds, public disclosures and its own research, and sells access to it separately as an API. The open-source packages it analyses are public, so a funded rival scanning the same registries could accumulate comparable coverage with time and effort. |
Checkmarx sells to the enterprise security and application-security team that owns the code its developers ship, and it frames the problem as securing that code from creation through runtime. The about page describes protecting the software that powers banks, hospitals, governments and the products millions of people rely on, which is the regulated end of the market rather than the self-serve end.
The commercial motion is sales-led with a self-service front door. The packaging page invites a buyer to pick the scanning modules that match its attack surface and get a custom quote, with Checkmarx One included as the platform foundation, so a prospect can assemble a bundle and review the selection before requesting a quote, and the page shows no price.
A newer segment is the team adopting AI coding assistants. Forrester reports that wider adoption of AI coding assistants and agents increases the amount of code that has to be secure before deployment, and Developer Assist runs inside Cursor, Windsurf, VS Code and JetBrains alongside the assistants writing that code.
Checkmarx One pairs proprietary scanners with a correlation layer rather than only aggregating other tools. Static analysis runs on a hybrid engine, dependency analysis adds exploitable-path reachability that determines which vulnerable third-party functions an application may call at runtime, and an API engine reads source code and documentation to find the undocumented, shadow and zombie endpoints that gateways and firewalls miss. Infrastructure-as-code, secrets, container and dynamic testing run beside them, and the ASPM layer blends exploitability, reachability, fixability and runtime exposure into one risk score.
The agent layer moved from announcement to delivery in July 2026. Developer Assist runs a continuous find-and-fix loop inside the editor, and the Triage and Remediation agents separate exploitable risk from severity noise using what Checkmarx calls attackability, then open merge-ready pull requests that developers review before merging.
Checkmarx Fusion is the newest and least examined capability. It runs a curated set of vendor-validated large-language models beside the rules-based scanner, on the argument that rules cover what code contains rather than how it executes, and Checkmarx bounds the model set to keep scanning costs predictable. The reviewed sources carry no independent evaluation of its accuracy, so the fidelity claim rests on the vendor's own measurement.
Checkmarx has enterprise traction, and most of the numbers behind it come from Checkmarx. A March 2023 ChannelPro article states the company served more than 1,800 customers, the most recent count from an outside source in the reviewed record. The about page adds its own figures, saying nine analyst firms rate Checkmarx a leader and that Checkmarx One passed 150 million dollars in annual recurring revenue within three years.
Checkmarx opened a federal channel in June 2026. Carahsoft became its Master Government Aggregator, selling the platform through NASA SEWP V, the E&I Cooperative Services Contract and The Quilt, which are contract vehicles agencies buy through, and Checkmarx One for Government has held a FedRAMP Moderate certification since 12 June 2026. That pairs an authorization with a route to federal buyers, which is access rather than recorded demand, and the reviewed sources name no agency purchase.
The agent business has one named account rather than none. PatientPoint's application security engineer described the Triage and Remediation agents identifying false positives and letting developers review before merging, the one customer voice on the AI layer in the reviewed record. The reviewed sources carry no adoption figure for that layer, and no independent benchmark of it appears in the reviewed sources.
Checkmarx publishes a bundle configurator rather than a rate card. The packaging page invites a buyer to pick the scanning modules that match its attack surface, keeps Checkmarx One as the platform foundation underneath them, and ends in a review step before a custom quote is requested, so the shape of the commercial offer is public even though the price is not.
That structure fits a vendor selling to procurement-gated enterprises and governments rather than to individual developers. The reviewed sources disclose no list price, no per-seat figure and no per-scan figure for either the platform or the agents.
Checkmarx One is delivered as one platform that fits into the workflows a team already runs. It integrates with existing development and security workflows including editors, source-control systems, build pipelines and ticketing systems, and Checkmarx says it spans more than 75 languages and 100 frameworks. The ASPM layer consumes SARIF results so a customer can bring findings from other application-security tools into the same correlated view.
Operations target developer-speed feedback inside that workflow. Scanning runs as code is written in the editor and again through the build, and the risk layer blends exploitability, reachability, fixability and runtime exposure into one score so a team fixes what matters rather than chasing every result.
The agent layer delivers inside developer tooling rather than as a separate console. Developer Assist runs in AI-native editors alongside coding assistants, keeps source code on the developer's machine and sends only minimal metadata, and applies validated fixes in place. Checkmarx backs the hosted platform with daily backups of customer data retained for seven days and encryption at rest.
Checkmarx documents the assurance program an enterprise code-security buyer checks. The trust center lists ISO/IEC 27001:2022 certification, an annual independent SOC 2 Type II audit available on request, and alignment with the NIST Secure Software Development Framework. Checkmarx One for Government holds a separate FedRAMP Moderate certification, certified since 12 June 2026, a federal authorization recorded on the government's own marketplace.
The readiness item a buyer raises first is Checkmarx's own 2026 compromise. Attackers reached its GitHub repositories through the Trivy supply chain attack and published malicious code in externally distributed artifacts including VS Code extensions, GitHub Actions workflows and a Jenkins plugin. A SecurityWeek article states that Lapsus$ listed Checkmarx on its leak site claiming stolen source code, employee databases, API keys and database credentials, and that the attackers exfiltrated data from the GitHub environment on 30 March.
The disclosure itself is the counterweight. Checkmarx published a dated incident record, named Mandiant as its investigator, and reported in July 2026 that the investigation was complete, the incident contained, the AWS production environment unaffected and the Checkmarx One service never accessed. A BleepingComputer article lists the clean replacement versions of the affected artifacts. A buyer can therefore audit the sequence rather than take a summary on trust, which is what makes the incident assessable at all.
Checkmarx One is built to be the single application-security platform for a development organization. It consolidates static, dependency, infrastructure-as-code, secrets, container, API and dynamic testing under one correlation layer, so a buyer can replace fragmented point tools with one vendor, and its own comparison page argues that lightweight open-source static analysis leaves gaps a consolidated platform closes.
Outward, Checkmarx One integrates with the wider developer ecosystem rather than tying a customer to one stack. It consumes SARIF results from other application-security tools, correlates code-to-cloud signals with findings from third-party tools and cloud-security platforms, and the Developer Assist agent connects to AI-native editors and coding assistants. Checkmarx also sells its malicious-package data on its own through an API that a customer can call before downloads, inside build pipelines, or before a package enters a private registry.
Inward, adoption concentrates a customer's scanning, correlation, risk scoring and remediation history with one vendor. That concentration is the value a buyer consolidates onto, and the 2026 compromise of Checkmarx's own distributed artifacts is the argument a buyer wary of single-vendor dependence will raise against it.
Checkmarx pairs a founder who built the company with a chief executive who has sold security companies before. Maty Siman has overseen technology as founder since 2006. Co-founder Emmanuel Benzaquen led the company for 17 years and stayed on the board after the 2023 transition a March 2023 ChannelPro article records.
Sandeep Johri founded and sold Oblix to Oracle and Determina and Bluelane to VMware, then ran Tricentis for seven years and earlier grew HP's software division. Checkmarx states those prior exits on its own about page, and a March 2023 ChannelPro article records the appointment. Hellman and Friedman closed a 1.15 billion dollar acquisition of Checkmarx in April 2020, with TPG and Insight Partners taking minority interests.
The AI bench came partly by acquisition. A SecurityWeek roundup states that the December 2025 Tromzo deal brought a team specializing in autonomous security agents into the product and engineering organization, Checkmarx said in December 2025 that the Tromzo reasoning engine would power new Assist agents from early 2026, and the Assist agents reached general availability in July 2026. Checkmarx says its engineering teams in the United States, India, Israel and Portugal work on machine-learning models for novel vulnerability classes and on agentic systems that triage and remediate findings.
