Your Application
Deserves Better Security.
Unlike firms that spread thin across every service, Cylent specializes in offensive application security — led by engineers trusted by Fortune 100 companies.
Too many firms deliver recycled reports and move on. At Cylent, every engagement is senior-led, exploit-driven, and validated with re-testing — so you don't just get findings, you get outcomes.
Expert-Led Application Security.
No Juniors. No Shortcuts. No Bullshit.
Most firms dilute security into every service under the sun — red teaming, phishing campaigns, even CISO-for-hire. The result? junior testers and shallow reports.
At Cylent, we focus on one thing and do it at the highest level: offensive application security. Every engagement is led by senior engineers with Fortune 100 experience, delivering:
Senior-Led Engagements — no interns, no outsourcing, just experts.
Penetration Testing Reports that go beyond findings, with clear remediation steps.
Re-Test Included — fixes validated, so you know risks are closed.
Client-Facing Reports — designed for executives and auditors, not just engineers.
Exclusive Engagements — we never stack projects. Your app gets our full attention.
