Your managed security and compliance partner for SaaS, tech, and enterprise teams

In a market split between Fortune-500 consultancies and compliance platforms, we operate the middle ground — a managed security function that delivers continuous compliance, continuous monitoring, and senior expertise across the full security lifecycle.

See how we work

OUR MISSION

Operate the security function that scales with your business

We treat security as a strategic capability — not a compliance task. With over a decade of experience operating security programs across regulated SaaS, fintech, and healthcare, we know what mature, scaled security looks like — and how to build it.

Built for security buyers in
SaaS, tech, and growing enterprises

Most cybersecurity firms either target massive enterprises with multi-year engagements or sell one-size-fits-all platforms. We operate differently — as a managed security partner for companies that need full-stack security expertise without the cost or wait of building it in-house.

  • Full security lifecycle coverage

    Compliance, cloud, SecOps, testing, and SDLC — one provider across the full security lifecycle

  • Engineering-integrated security

    Security operations designed to integrate with your engineering workflow, not slow it down

  • Operational ownership

    We don’t just deliver findings — we implement, remediate, and evolve your security program as your business changes

  • Built for mid-market complexity

    Calibrated for companies where security is a board-level concern but doesn’t yet justify a 50-person in-house team

Enterprise-grade processes, delivered at your pace

Protagonist is built on the foundation of a 500+ person technology services firm with a decade of operating experience and 200+ delivered projects across SaaS, fintech, healthcare, and Fortune 500 clients.

  • Predictable outcomes

    Mature delivery processes — security outcomes delivered on schedule, with defined scope, milestones, and owners.

  • Faster time to value

    Proven playbooks for compliance programs, cloud hardening, and managed detection — we operate from day one instead of designing on the fly.

  • Professional execution

    Consistent quality from onboarding to incident response — backed by documented runbooks, defined SLAs, and a delivery system that’s been operating for over a decade.

  • Scalable partnership

    Engagements scale up and down as your needs evolve — from a single service line to a fully managed security function.

What drives us

We’re security partners who believe that great security should accelerate your business, not slow it down.

  • Ownership over reports

    Most security firms deliver reports and walk away. We remediate. When we find a vulnerability, we close it. When we identify a control gap, we implement the fix. Security outcomes are our responsibility, not just our recommendations.

  • Security as strategy

    Security is a business capability, not a compliance tax. Every control we implement, every process we design, and every audit we prepare is calibrated to one goal: removing security as a friction point in your sales cycle, your roadmap, and your growth.

  • Built for builders

    We work fluently inside modern engineering stacks — CI/CD pipelines, containerized deployments, infrastructure as code, cloud-native architectures. Our security implementations integrate with your development workflow because we design them with engineers, not for them.
