Your dedicated security partner.

We exist to make practical, high-impact cybersecurity accessible — without the cost, complexity, and overhead of large consulting firms.

Who we are

Practitioners first. Consultants never.

CyberNerds is a practitioner-led security firm headquartered in Thanjavur, Tamil Nadu. Our team holds certifications like OSCP, CISA, CISM, CEH, and GIAC specializations — people who test, defend, and audit systems for a living, not account managers reading from slide decks.

  • 200+ security engagements delivered
  • 98% of clients stay with us
Why it matters

Recognized by the government. Trusted by regulators.

We're empaneled by CERT-In and TNEGA as a security auditor — a vetting most firms never pass. That means our assessments are recognized where it counts: RBI, SEBI, IRDAI, UIDAI, and government tenders.

What we
believe

The principles behind every engagement — the reasons clients stay.

Impact over noise

We report the handful of findings that would actually get you breached — not a scanner's thousand-line dump. Every issue is real, ranked, and fixable.

Hands on keyboard

Certified engineers do the work — manual testing, real exploitation, human judgement. No junior staff learning on your systems.

We close the loop

Finding a problem is half the job. We hand you fix guidance and retest for free until the gap is genuinely closed.

Built for India

RBI, SEBI, IRDAI, UIDAI, CERT-In, DPDPA — we speak the regulators fluently, so compliance is a byproduct of good security, not a scramble.

Accessible by design

Enterprise-grade security without the enterprise price tag or six-month engagements — practical programs scoped to what you actually need.

Partners, not vendors

98% of clients stay with us because we act like part of your team — a call away, invested in your security maturity over years, not one report.
