Sentry · Defensive Security

Managed Defense

Your port in the storm.

In an uncertain and ever-changing cybersecurity landscape, every company needs a safe harbor. Sentry is NaviSec's defensive practice. We believe in the defense-in-depth model — security is like the layers of an onion — and in discussing where you are in your security program with integrity, making incremental improvements rather than promising to make you 'unhackable.'

What's included
🛡️

MDR + IH/IR

Managed detection & response powered by CrowdStrike, with incident handling and incident response when something gets through.

📧

Email & Awareness

Secure email gateway plus managed security awareness training through KnowBe4 and Symbol Security — because your people are the first line of defense.

🕵️

Darkweb Monitoring

Darkweb search and monitoring to surface exposed credentials and company data before attackers use them.

Philosophy

Defense in depth, without the buzzwords.

There are seemingly thousands of defensive solutions available, some promising to make you "unhackable." We take a different approach: an honest conversation about where your security program stands today, and a layered defense built incrementally against your largest organizational technology risks.

Sentry interlinks with Delta (offensive testing validates the defenses) and Atlas (24/7 monitoring watches them) — so your defensive posture is tested, watched, and improved continuously.

Security is a journey, not a destination

Build a defense that fits your business.
