Offensive security for the full application surface — web, mobile, smart contracts, and infrastructure.
OnSecOps is a specialist penetration testing company for funded startups and scale-ups. We manually test what your product is built from, give your engineers fixes they can ship, and deliver audit-ready reports that directly support your SOC 2, HIPAA, and ISO 27001 compliance — the exact evidence your auditors and reviewers ask for.
One partner for the entire application attack surface
We test the things modern software is actually built from — and help your team keep them secure.
Web Application Penetration Testing
Manual, methodology-driven testing of web apps and APIs against OWASP Top 10, ASVS, and the API Security Top 10. We find the business-logic and access-control flaws scanners miss.
Learn more →Mobile Application Penetration Testing
iOS and Android assessments aligned to OWASP MASVS. Static and dynamic analysis, traffic interception, and backend API testing.
Learn more →Smart Contract Audit
Line-by-line review of Solidity / EVM contracts combining manual analysis with tooling. We catch reentrancy, access-control, and economic-logic flaws before mainnet.
Learn more →DevSecOps
Security embedded into your CI/CD — SAST, DAST, SCA, secrets and IaC scanning, container and pipeline hardening. Continuous assurance, not point-in-time.
Learn more →Network Penetration Testing
External and internal infrastructure testing — segmentation, lateral movement, privilege escalation, and configuration review.

A reviewer asks for a penetration test. We give you the report, the severity-rated findings, and the remediation retest that closes the item — mapped to the framework you're being assessed against.
A clear, senior-led process from scope to attestation
You work directly with the person doing the testing at every step.
Scoping
We define targets, rules of engagement, and objectives on a short call.
Reconnaissance & threat modeling
We map the real attack surface before testing begins.
Manual testing
Hands-on exploitation, not just a scan — chained, real-world attack paths.
Reporting
Executive summary plus technical findings with reproduction steps, evidence, CVSS severity, and developer-ready remediation.
Remediation retest
We re-test fixed issues and issue an attestation letter at no extra cost.
Depth, not dashboards
Senior-only, founder-led
Every test is run by an OSCP/OSCE-certified tester with a PhD in Cybersecurity. No hand-off to juniors.
Manual-first, not scan-and-forward
We report what's actually exploitable and chain findings the way a real attacker would.
Full attack surface, one partner
Web, mobile, smart contracts, network, and the DevSecOps to keep them secure.
Reports your developers can act on
Clear reproduction, root cause, and fix guidance — not a raw tool dump.
Retest included
We verify your fixes and give you attestation, not just a list of problems.
Built for US teams
Overlapping working hours and async-friendly communication.
A report your engineers and your auditors both trust
- Executive summary — written for leadership and the board.
- Technical findings — severity (CVSS), affected assets, reproduction steps, evidence, and remediation guidance.
- Compliance mapping appendix — tying findings to your framework's controls.
- Remediation retest + attestation letter — we verify the fixes and document closure.
- Live debrief call — with your engineering team.
Report anatomy
Every finding is rated, reproducible, and mapped to a fix. The severity scale below is illustrative of our reporting — not drawn from any client engagement.
- Executive summary — board-level risk narrative.
- Technical findings — CVSS, evidence, reproduction, fix.
- Compliance mapping appendix — controls tied to findings.
- Retest + attestation letter — proof the item is closed.
Trusted by modern engineering teams
Credibility you can verify
We don't post quotes you can't check. Credibility here comes from verifiable credentials and public technical work — OSCP and OSCE certifications, a PhD in Cybersecurity, and ongoing security writing.
OSCP
Offensive Security Certified Professional — hands-on exploitation under exam conditions.
OSCE
Offensive Security Certified Expert — advanced exploitation and evasion.
PhD in Cybersecurity
Doctoral research in security — depth beyond the certification checklist.
