ESET

• MSSP Alert reported in 2024 that Microsoft held a dominant 40.2 percent of endpoint protection. ESET's measured edge over Microsoft in the reviewed record is one test round, at 100 percent protection to 99.1 percent in AV-Comparatives' late-2025 business test. A later round in which Microsoft matches that score would remove one documented differentiator ESET has against the share leader.
• AV-Comparatives modeled ESET's five-year cost per protected computer at 2,132 dollars against CrowdStrike's 1,245, even though ESET's licence price was the lower of the two. A buyer who reads that model closely may discount ESET's price advantage.
• ESET's 500,000 business customers and 733 million euros of 2025 revenue are figures ESET publishes about itself, and no third-party measurement of either appears in the reviewed record, so a buyer who requires verified vendor scale has nothing to check them against.

ESET sells against a threat that shows up in government records. CISA published an alert on the Industroyer grid malware stating that its incident center was working to validate the ESET and Dragos analysis of the attack platform used against Ukrainian infrastructure. The National Vulnerability Database record for a WinRAR flaw that attackers were exploiting in the wild lists ESET as its source and credits three ESET researchers by name with the discovery.

The buyer, though, is almost everyone. ESET counts 500,000 business customers across 178 countries and territories, and its consumer line claims technology trusted by over a billion users. The business site runs verticals for finance, education, manufacturing, government, and healthcare alongside a small-office product for up to 25 devices.

ESET sells to a home user, a small office of up to 25 devices, and a government buyer under one brand. The reviewed record does not size the endpoint problem for any of those buyer types, so a buyer comparing vendors has ESET's coverage claim and no number for its own kind of organization. [s14, s12, s2, s19]

ESET builds its business-security portfolio around one platform and one reputation database. ESET PROTECT Platform ships in tiers from Entry to Elite and uses LiveSense, the company's layered detection technology, and LiveGrid, a cloud reputation system ESET describes as global. ESET Inspect adds behavior and reputation detection on top, feeding security teams real-time judgments drawn from that same system.

AV-Comparatives ran ESET PROTECT Entry against 461 real-world test cases between August and November 2025 and recorded 461 blocked, a 100 percent protection rate with six false alarms, ahead of CrowdStrike at 99.3 percent, Microsoft at 99.1 percent, and Sophos at 98.0 percent. MITRE included ESET among eleven vendors in its 2025 ATT&CK Evaluations, run against emulations of Scattered Spider and Mustang Panda.

The response half tests less cleanly. AV-Comparatives certified ESET in its 2025 endpoint prevention and response test, recording 98.0 percent combined prevention and response capability, then charged the product a moderate operational-accuracy cost. The lab's five-year cost model puts ESET at 2,132 dollars per protected computer, above CrowdStrike at 1,245, even though ESET's licence price of 152 dollars was among the lowest tested. [s3, s5, s8, s10, s9]

ESET competes for endpoint budget against Microsoft. MSSP Alert reported in 2024 that Microsoft held a dominant 40.2 percent share of endpoint protection, with CrowdStrike second at 14.2 percent, and it names Defender for Endpoint as Microsoft's offering in that market. ESET answers with detection results that beat both in the same AV-Comparatives run. In the lab's separate response test, ESET's licence price was among the lowest of the field.

ESET's analyst placements differ by market. ESET displays a Challenger placement in the 2026 Gartner Magic Quadrant for Endpoint Protection and a KuppingerCole Market Leader position in managed detection. ESET publishes those placements on its own pages, so a reader gets the company's account of them rather than the reports.

ESET runs from Bratislava, and Spain's National Cryptologic Centre certified ESET Endpoint Security under Common Criteria in February 2026, with a named testing laboratory doing the evaluation. A rival can pursue the same Common Criteria certification, and the reviewed record documents no buyer choosing ESET for its European base. ESET therefore competes on measured protection, where AV-Comparatives scored it above both Microsoft and CrowdStrike, and a buyer can verify the certificate on the Spanish register as one credential among several. [s18, s8, s6, s16, s15]

ESET publishes scale figures that no third party in the reviewed record measures, so a buyer sizing the company works from ESET's numbers alone. The company counts 500,000 business customers across 178 countries and territories and more than 30 years of operation, and its consumer line claims technology trusted by over a billion users. ESET reported 733 million euros of revenue for 2025, up 6 percent, with business customers driving the growth.

Recognizable brands appear at the enterprise end. ESET's business pages carry a logo wall naming Canon and Mitsubishi Motors as protected customers, set beside unattributed deployment sizes running to tens of thousands of endpoints, with T-Com listed as a security partner. Logos show recognition rather than deployment, and ESET is the party presenting them.

Distribution runs through partners and a self-serve consumer store. ESET operates reseller, managed service provider, technology alliance, and affiliate programs, and it sells home subscriptions directly by device count and year. Buyers can start a business trial without a credit card. [s2, s19, s7, s3, s4]

ESET's research is the part of the company outsiders cite. CISA's alert on the Industroyer grid malware states that its incident center worked to validate the ESET and Dragos analysis. The National Vulnerability Database record for the WinRAR path traversal flaw lists ESET as its source and credits Anton Cherepanov, Peter Košinár, and Peter Strýček with finding a flaw attackers were exploiting in the wild. Help Net Security covered ESET's APT Activity Report for October 2025 through March 2026 on its own pages, reporting the company's account of Chinese, North Korean, Russian, and Iranian activity.

The company's lineage is long and its ownership is private. Rudolf Hrubý, Peter Paško, and Miroslav Trnka founded ESET in Slovakia on 1 January 1992, and it remains a private limited company headquartered in Bratislava. [s12, s14, s17, s2, s16]

ESET publishes its security posture through a trust portal anyone can read without signing in. The portal at trust.eset.com lists ISO/IEC 27001:2022, ISO 9001:2015, SOC 2 Type 2, Common Criteria, ENS, DORA, GDPR, Cyber Essentials Plus, and VPAT, with the underlying documents available on request.

One credential is verifiable outside ESET entirely. Spain's National Cryptologic Centre lists ESET ENDPOINT SECURITY V12.1.2057.3 in the endpoint detection and response category, certified 24 February 2026 against Common Criteria version 3.1 release 5, with jtsec Beyond IT Security recorded as the testing laboratory. That record sits on a government certification body's site, which is a different class of evidence from a badge on a vendor page.

The National Vulnerability Database published a local privilege escalation flaw in the ESET Inspect Connector in July 2026, caused by improper authentication in an inter-process channel, and the cited record does not show it exploited. That flaw is in ESET Inspect, and the certificate on Spain's register is for ESET Endpoint Security, so the government record covers a different product from the one with the defect. [s20, s15, s13]

Add analyzed competitors to compare them side by side with ESET.

ESET sells across the whole width of the market rather than to one segment. It reports 500,000 business customers across 178 countries and territories, and its consumer line claims technology trusted by over a billion users. The business site runs a Small Office product for up to 25 devices at one end and ESET PRIVATE tailored solutions for large organizations and public institutions at the other.

Business customers led the growth. ESET reported 733 million euros of revenue for 2025, up 6 percent, and named business customers as the driver. That split matters because the consumer base is a subscription renewal business, while the business base is what carries the platform, the managed service, and the intelligence subscription.

ESET's business navigation lists finance and banking, education, manufacturing, government, and healthcare, and a Spanish government body has certified ESET Endpoint Security under Common Criteria. The reviewed record does not measure how much revenue those sectors produce, so that navigation describes what ESET sells to rather than where its revenue comes from.

ESET builds its prevention and detection on two shared assets. ESET PROTECT Platform uses LiveSense, the company's layered detection technology, and LiveGrid, a cloud reputation system ESET describes as global, and ESET Inspect reads from that same reputation system to deliver behavior-based detection to security teams. The platform adds server security, mail security, encryption, multi-factor authentication, patch management, and cloud workload protection as modules.

AV-Comparatives ran ESET PROTECT Entry against 461 real-world test cases between August and November 2025 and recorded 461 blocked, a 100 percent protection rate with six false alarms, ahead of CrowdStrike at 99.3 percent, Microsoft at 99.1 percent, and Sophos at 98.0 percent. MITRE included ESET among eleven vendors in its 2025 ATT&CK Evaluations, run against emulations of Scattered Spider and a Chinese state-sponsored group.

ESET headlines its homepage with AI-native prevention for tomorrow's threats, on a page that also credits more than 30 years of human expertise. Its MDR page describes a human-led service that uses AI alongside indicators of compromise, indicators of attack, and user behavior analytics. The homepage and MDR descriptions are ESET's own, so the part a buyer can check is the detection AV-Comparatives and MITRE measured.

ESET reaches business buyers through partners and a self-serve path for small orders. The business page offers a quote, a partner purchase, or an online purchase for up to 100 devices, and ESET runs reseller, managed service provider, technology alliance, affiliate, and referral programs. Larger deals route to ESET PRIVATE, the tailored track for enterprises and public institutions.

Evaluation is free. ESET offers a business trial with no credit card and a pre-built demo, so a prospect can try the product before buying it.

The named references cluster at the enterprise end. ESET's business pages carry customer logos naming Canon and Mitsubishi Motors alongside deployment tenures and sizes running to more than 32,000 endpoints, and list T-Com separately as an ISP security partner rather than a protected customer. ESET publishes the logos, the tenures, and the deployment sizes, and the reviewed sources carry no third-party account of any of them, so a buyer checking references has ESET's account alone.

ESET sells small orders online and negotiates large ones. Home subscriptions sell by device count and subscription year straight from the site, business orders up to 100 devices can also be bought online, and anything larger routes to a quote or a partner. The unit of charge for the endpoint products is the device.

One outside source puts a number on the business list price. AV-Comparatives, which collected list prices from vendors for its 2025 endpoint prevention and response test, modeled ESET at 152 dollars per agent over five years for a hypothetical 5,000-client deployment, against CrowdStrike at 475 and Elastic at 167.

The same lab then argues the cheap licence is not the whole cost. AV-Comparatives charged ESET a moderate operational-accuracy cost and modeled a five-year total cost of ownership of 2,132 dollars per agent, against CrowdStrike at 1,245 and Elastic at 739.

ESET lets the customer choose where the management plane runs. ESET PROTECT Platform deploys in the cloud or on the customer's own servers, and ESET states that cloud deployment carries the widest range of benefits. That choice is itself a feature for buyers whose regulators or internal policy rule out a vendor-hosted console.

The managed service is where ESET takes work off the customer. ESET MDR runs around the clock, and the company describes a human-led service that uses indicators of compromise, indicators of attack, user behavior analytics, machine learning, and internal and external intelligence feeds to reveal malicious activity and then perform containment and eradication. Higher tiers add retrospective threat hunting and custom reporting.

AV-Comparatives certified ESET in its 2025 endpoint prevention and response test, recording 96.7 percent active response, 99.3 percent passive response, and 98.0 percent combined, then charged the product a moderate operational-accuracy cost. The lab carries that moderate rating into its five-year cost model, which puts ESET at 2,132 dollars per agent against CrowdStrike's 1,245.

ESET runs a trust portal anyone can read without signing in. The portal at trust.eset.com lists ISO/IEC 27001:2022, ISO 9001:2015, SOC 2 Type 2, Common Criteria, ENS, DORA, GDPR, Cyber Essentials Plus, and VPAT, with the underlying documents available on request. The company's compliance page separately states that ESET has achieved SOC 2 Type 2 attestation.

One credential is verifiable outside ESET entirely. Spain's National Cryptologic Centre lists ESET ENDPOINT SECURITY V12.1.2057.3 in the endpoint detection and response category, certified 24 February 2026 against Common Criteria version 3.1 release 5, with jtsec Beyond IT Security recorded as the testing laboratory. A government certification body's own register is a different class of evidence from a badge on a vendor page.

The National Vulnerability Database published a local privilege escalation flaw in the ESET Inspect Connector in July 2026, caused by improper authentication in an inter-process channel. The cited record does not show that flaw exploited in the wild. The certificate on Spain's register is for ESET Endpoint Security, so the government record covers a different product from the one with the defect.

ESET has converged its business portfolio onto one console. ESET PROTECT Platform sells in tiers from Entry through Elite to MDR, with endpoint protection, extended detection, mobile threat defense, server security, encryption, multi-factor authentication, mail security, cloud application protection, patch management, threat intelligence, and cloud workload protection as modules under it. ESET publishes an integrations page for connecting the console to other vendors' tools.

The reputation system is the shared layer underneath. ESET describes LiveGrid as a cloud reputation system using data from ESET users worldwide, and ESET Inspect draws its real-time judgments from it, so the detection work is pooled rather than rebuilt per product. ESET Threat Intelligence sells a subscription built on telemetry ESET says covers regions other vendors see poorly.

ESET exports its detections and intelligence to other vendors' tools through a public REST API and STIX feeds, so outside tools can consume ESET data. The reviewed sources name no third party building its own products on ESET and no marketplace of customer-authored extensions, so on this record ESET reaches other tools primarily as a data source, and whether an outside developer base exists is not something the reviewed sources settle.

ESET's research organization is what outsiders cite. CISA's alert on the Industroyer grid malware states that its incident center worked to validate the ESET and Dragos analysis, and Help Net Security reported ESET's October 2025 through March 2026 APT findings as news on its own pages. The National Vulnerability Database record for the WinRAR path traversal flaw lists ESET as its source and credits Anton Cherepanov, Peter Košinár, and Peter Strýček with finding a flaw attackers were exploiting in the wild.

ESET credits telemetry from regions it says other vendors cover poorly for its earlier detection of APTs and malware, and it reports more than 30 years in the market. The telemetry claim and the 30-year figure both come from ESET, and no independent measure of that telemetry reach appears in the reviewed sources, so a buyer weighing the earlier-detection claim works from ESET's own account.

Rudolf Hrubý, Peter Paško, and Miroslav Trnka founded ESET in Slovakia on 1 January 1992. It is a private limited company headquartered in Bratislava that publishes its own annual results.
