Türkiye-based cybersecurity developer C-Prot has joined the Deloitte Technology Fast 50 Türkiye 2026 list, according to its October press release. The recognition is the company's second reported appearance in the programme after 2023.
Alongside its latest growth recognition, the company is highlighting endpoint detection and response performance across Windows, Linux and macOS, a broad anti-fraud security portfolio and plans to expand internationally. Its Fast 50 rank and revenue-growth percentage have not been disclosed in the supplied release.
C-Prot Makes Its Second Reported Fast 50 Appearance
C-Prot, a Türkiye-based developer of endpoint protection technologies, has been included in the Deloitte Technology Fast 50 Türkiye 2026 programme, according to its October press release. The company says it also appeared in the ranking in 2023, making 2026 its second reported inclusion.
The 2026 programme recognises companies on the basis of growth in net sales revenue over a three-year assessment period, according to Deloitte's published programme framework and coverage of the September 2026 results. C-Prot's release does not disclose its position in the 2026 ranking, growth percentage or revenue figures. None should be inferred from its inclusion.
A Revenue-Growth Ranking, Not a Cybersecurity Certification
Deloitte Technology Fast 50 Türkiye measures company growth rather than the effectiveness of particular security products. The annual programme provides a measure of commercial expansion among technology companies that develop their own products and solutions.
C-Prot founder and chief executive S. Bilgehan Üstündağ said the company's return to the list after 2023 reflected its approach to growth. He argued that cybersecurity claims should ultimately be demonstrated through measurable results. The distinction is useful: a growth ranking can establish business momentum, but it cannot validate how well a product prevents an intrusion or contains an incident.
C-Prot Highlights Cross-Platform Endpoint Telemetry
Alongside the Deloitte recognition, C-Prot points to the performance of its antivirus and endpoint detection and response (AV/EDR) technologies in the EDR-Telemetry Project. The company reports that its solution led the platform's comparative telemetry results for Windows, Linux and macOS in September 2026.
In a separate company statement published in September, C-Prot gave scores of 39.60 for Windows, 25.60 for Linux and 38.50 for macOS. It said the macOS score had increased from 34.40, when its product was ranked second, to 38.50 in the updated evaluation. These figures are company-reported results of the project's scoring and may change as products and methodology evolve.
Telemetry Visibility Does Not Equal Protection Effectiveness
The EDR-Telemetry Project says its evaluations compare the amount and type of endpoint data exposed by EDR products under a documented methodology. The project explicitly cautions that telemetry scores do not measure malware-prevention efficacy, detection accuracy, response performance or overall product quality.
That caveat is especially important for potential customers in defence and other high-assurance sectors. Telemetry depth can support incident investigation and threat hunting, but procurement assessments also require prevention testing, incident-response validation, system compatibility, reliability, configuration review and operational support analysis. C-Prot's telemetry standing should therefore be read as evidence of a specific technical dimension rather than a universal global cybersecurity ranking.
The Product Portfolio Extends Beyond Endpoint Protection
The company's core offering covers endpoint antivirus and EDR protection for organisational workstations and servers. C-Prot also describes a wider portfolio covering mobile-application security, web-based fraud prevention, behavioural biometrics, call-related fraud prevention, cyber-threat intelligence and malware sandboxing.
C-Prot says these technologies serve customers across government, defence and financial services. It also states that its solutions are deployed across the mobile and digital banking channels of major Turkish banks and protect millions of users. The press release does not provide customer names, deployment counts or audited user figures for those claims.
Certifications and Industry Membership Form Part of the Company's Positioning
C-Prot's press release states that the company has been a member of the Anti-Malware Testing Standards Organization (AMTSO) since 2017. It also lists Microsoft Virus Initiative, VB100, OPSWAT Platinum and SKD Labs StarCheck among its credentials.
The release does not include certificate identifiers, validation links, product-version coverage or expiry dates. These references are therefore included as claims made by the company; they should be checked against the relevant schemes if used in a formal security procurement or due-diligence assessment.
Export Partnerships Are the Next Stated Priority
C-Prot says it is accelerating its international activity and seeking partnerships in additional countries. Üstündağ described artificial intelligence as a factor changing the speed and scale of attacks and said the company is adjusting its product roadmap to the evolving threat environment.
The October release does not identify new export destinations, signed overseas contracts, revenue targets or implementation timetables. The strategy is therefore best characterised as an international-growth objective rather than a disclosed set of contracted commercial milestones.
Implications for Türkiye's Cybersecurity Industrial Base
C-Prot's inclusion in a revenue-growth ranking is relevant to Türkiye's wider effort to develop proprietary cybersecurity technology. Its cross-platform endpoint tools and anti-fraud products address functions that can matter to military networks, public institutions and critical financial services, although suitability for any particular sensitive environment must be demonstrated separately.
Three developments would make the next stage of growth easier to assess: publication of the company's precise Fast 50 ranking and revenue-growth percentage, repeatable independent security-performance results beyond telemetry coverage, and identifiable overseas customer or partnership milestones. Until those are available, the strongest verified story is C-Prot's 2026 Fast 50 inclusion together with its stated product and export strategy.
