“Security leadership that speaks to boards, satisfies auditors, and protects what you’ve built.”

Bogdan Frincu — Founder & Fractional CISO, RoninSec

The Problem

Most Growing Businesses Are One Breach Away From a Crisis

Cyber threats don’t distinguish between startups and enterprises — but your security programme probably still does.

💸

Full-Time CISOs Are Unaffordable

A senior CISO costs $250k–$400k/year in salary alone. Most scaling businesses need the expertise but not the overhead — there is a smarter way.

📋

Compliance Is Getting Harder

ISO 27001, SOC 2, GDPR, NIS2, DORA — the regulatory landscape is expanding fast. Falling behind means lost deals, failed audits, and regulatory fines.

🎯

Board Expectations Have Shifted

Investors, enterprise clients, and regulators now demand demonstrable security governance. A tick-box approach no longer cuts it.

About

Your Fractional CISO

Bogdan Frincu — Fractional CISO
Bogdan Frincu Fractional CISO · RoninSec

Security leader. Technical practitioner. Trusted advisor.

I founded RoninSec to give scaling businesses access to the same calibre of security leadership that Fortune 500s take for granted — at a price that makes commercial sense.

My background is deliberately dual-track: strategic CISO leadership built through enterprise roles at VOIS/Vodafone and Visma, combined with deep hands-on technical experience across offensive security and red-teaming. That attacker’s perspective isn’t a service I offer — it’s the lens through which I build your defences. Understanding how adversaries think means the security programmes I design are genuinely effective, not just checkbox-compliant.

I work directly with your leadership team to translate security complexity into business outcomes — clear roadmaps, board-ready reporting, and compliance programmes that actually get executed.

Why RoninSec

What Makes the Difference

🎯

Strategic + Technical

Most CISOs are boardroom strategists or technical practitioners. I am both — commercially sound advice that is also technically honest.

🧠

Attacker’s Mindset

Years of hands-on offensive security experience inform every defensive recommendation. I design programmes that stop real attacks, not just theoretical ones.

⚡

Structured Delivery

Proven methodologies compress months of security work into weeks — faster time to compliance, lower cost, and measurable outcomes for your business.

🌍

Jurisdiction-aware compliance advisory across all three major regulatory environments — GDPR, NIS2, DORA, HIPAA, SOC 2, and more.

📊

Board-Ready Reporting

💡

Flexible Engagement
