Cybersecurity & AI Executive
Security should be demonstrable, not just promised.
I build companies and security programs around that idea, turning cybersecurity, AI, and enterprise risk into decisions boards can act on.
I co-founded Tynrose Secure on a simple conviction: if your security can't be demonstrated, it doesn't count. Every engagement gets senior ownership and an evidence-backed path through CMMC, SOC 2, HIPAA, and NIST 800-171.
That conviction comes from twenty years inside companies of every shape, from venture capital to hospitality, watching organizations spend heavily on security they couldn't demonstrate. The evidence usually existed. Nobody could produce it when it mattered. I build companies that close that gap.
Today I lead security and operations at Tynrose, run PROTBYTE, where I build technology and AI compute infrastructure for companies, and develop Sentinel, the free scan that shows any organization where it actually stands. I'm based in Austin, Texas.
Everything answers the same question: can you prove where you stand?
Managed security, compliance, and IT for organizations that need to prove their posture, not just describe it. Senior-led engagements take clients from first gap assessment to passed audit, with evidence at every step.
The app I'm developing under Tynrose Secure: an external scan with no signup, no agent, and no sales call. Enter a domain and it analyzes email authentication, DNS, TLS, security headers, exposed assets, and known CVEs, then delivers a security score and a prioritized, executive-ready report.
Technology and AI compute infrastructure for companies: secure networking, continuity systems, and the platforms AI workloads actually need. Founded in 2024. Sentinel was first built here.
Visit protbyte.comCompliance should produce evidence you can hand to an auditor, a customer, or a board, not binders that age in a drawer. If it can't be demonstrated, it isn't done.
Detection, response, and governance designed so the answer to "can we?" is usually "yes, safely," measured in minutes and decisions rather than meetings.
Organizations should move fast with AI without moving carelessly. That takes real guardrails: governance, threat modeling, and infrastructure built for the workloads AI actually creates.
Technical risk translated into plain language and clear options. Executives shouldn't need a glossary to make a security decision.

Tynrose Secure is a managed security, compliance, and IT firm co-founded by Masoud Heydari. It guides clients through CMMC, SOC 2, HIPAA, and NIST 800-171 with senior ownership on every engagement and results clients can prove rather than just claim.
Tynrose Sentinel is a free external security scan that Masoud Heydari is developing under Tynrose Secure, available at sentinel.tynrosesecure.com, with no signup and no agent. It analyzes an organization's email authentication, DNS, TLS, security headers, exposed assets, and known CVEs, maps the findings to CMMC, NIST CSF, NIST 800-171, SOC 2, ISO 27001, PCI DSS, and HIPAA, and delivers a security score with a prioritized, executive-ready report.
He helps executives turn complex technical risk into decisions a board can act on, from strategy through hands-on execution. Typical work spans security architecture, compliance readiness for CMMC, SOC 2, HIPAA, and NIST 800-171, AI governance, and incident response.
PROTBYTE is a company Masoud Heydari founded in 2024 that builds technology and AI compute infrastructure for companies: secure networking, continuity systems, and the platforms AI workloads need. The domain-posture scanner that became Tynrose Sentinel was first built at PROTBYTE.
