The Open Security Experience
Discover Exposure.Prove What's Exploitable.Meet Aludra.
Operator-led penetration testing and AI-powered validation that shows what's exposed and proves what's exploitable.
Discover
See what's actually there.
Continuously identify assets, vulnerabilities, exposures, and changes. The environment comes into focus.
- Assets come into view
- Vulnerabilities surface
- Exposure becomes visible

Aludra
Validate
Prove what's real.
Finding something is not the same as proving it matters. Aludra keeps what is actually exploitable.
- Theoretical findings recede
- Exploitable exposure holds
- False positives drop away
Many findings → fewer validated exposures
Aludra
See & Act
Know what deserves action.
See and Act is when a validated finding becomes something the organization can move on, not another item on a longer list.
- Evidence lands in your client portal
- Priority and owner assigned
- Remediation is visible
Evidence → Priority → Owner → Remediation
Client portal
Improve
Prove you're getting stronger.
Open Security does not stop when something is fixed. The work is retested, measured, and run again.
- The fix is remediated
- The fix is retested
- The gain is validated
Remediated → Retested → Validated

The Open Security Experience
Continuous Exposure Validation, Led by Operators
Security isn't a point-in-time exercise. It's an ongoing cycle of discovery, validation, action, and improvement.
- Aludra discovers exposure
- Aludra proves what is exploitable
- Operators turn proof into action
- Aludra retests the fix




From Discovery to Proof to Remediation
Operators uncover and validate real exposure. Technology keeps that intelligence visible, actionable, and connected beyond the assessment.

Why Point-in-Time Testing Isn't Enough
Attack surfaces change daily. Continuous discovery, validation, action, and retesting keeps proof current instead of a snapshot.

There's a difference between believing you're secure and being able to prove it.
The Operator’s Perspective
Built by operators who do the work.
The people building our technology are the same operators testing environments, exploiting vulnerabilities, tracing attack paths, and helping teams fix what matters.
- Military Cyber Operations
- Offensive Security Research
- DEF CON / Black Hat
- Real-World Adversarial Testing

The Operator’s Perspective
Matt Toussain
Founder & Chief Information Officer
Offensive security operator, SANS instructor, and the founder behind Sirius — turning real attack experience into the methodology and tools other operators use.
- Offensive security
- Vulnerability operations
- Cybersecurity training

The Operator’s Perspective
Michael Pleasant
Chief Executive Officer
Marine Corps veteran and co-founder who built Open Security to make operator-grade cybersecurity accessible to the businesses that actually need it.
- Security leadership
- Veteran enterprise
- Client partnerships

The Operator’s Perspective
Josh Christman
Chief Operating Officer
COO who runs security engineering and the applied AI behind Aludra. Tests stay scoped to business risk. Findings stay ones an engineer will stand behind.

- Aludra
- Security engineering

The Operator’s Perspective
Bryce Zuccaro
Principal Security Engineer
Principal Security Engineer who plans engagements, mentors operators, and teaches the craft — SANS SEC460, Red Team Village, and the Las Vegas AI Security Forum.
- Penetration testing
- Adversary simulation
- Cybersecurity training

The Operator’s Perspective
Jacob Krut
Security Engineer
A self-taught security engineer who started in bug bounty by turning a blind SSRF in Yahoo Mail into remote code execution. The same instinct later found a high-severity SSRF in ChatGPT.
