Built by Hackers.
Trusted by Enterprises.

EncryptSec was founded by offensive security practitioners who got tired of watching enterprises fail at the same preventable attacks. So we built the firm we wished existed.

We Operate on One Assumption:
You're Already Breached.

Most security firms sell you confidence. We sell you clarity — about what's broken, what's exposed, and what you need to do about it. We don't tell clients what they want to hear.

EncryptSec was built by practitioners from red teams, SOCs, and incident response backgrounds across US, UK, Japan, and Korea. We've seen every type of breach. We've cleaned up after ransomware gangs, nation-state APTs, and opportunistic script kiddies alike.

That experience is what we bring to every engagement. Not slide decks. Not generic frameworks copy-pasted from NIST. Real-world adversarial thinking applied to your specific environment.

Assume Breach

01

We design every security program as if adversaries already have a foothold. This forces real defenses, not theoretical ones.

Attacker Mindset

02

Our defenders think like attackers. Understanding how systems are broken is the prerequisite to protecting them.

Radical Transparency

03

We tell you what's wrong, even when it's uncomfortable. Clients who know their real risk posture make better decisions.

Speed Matters

04

In cybersecurity, minutes cost thousands of dollars. We optimize everything — detection, response, remediation — for speed.

Market-Native

05

US, UK, Japan, Korea, Nepal, and other regions — we understand the regulatory environment, threat landscape, and business culture of each market.
