Built and led by former Stroz Friedberg leaders with decades of frontline experience.

Growth Changes the Risk Equation

Most MSPs were built for a different time. When environments were simpler, teams were centralized, and security and IT were treated as separate functions.

The fastest-growing companies don’t operate that way. They know they can’t.

As they expand, add systems, hire distributed and global teams, the stakes change. Risk doesn’t sit in one place anymore. And neither can the oversight around it.

Our cybersecurity services were built for this reality.

Why Security as a service matters now

Our Cybersecurity Services

Four core service areas that protect your organization and support how it grows.

Strategy & Leadership

As companies grow, security decisions increasingly shape business outcomes.

Our fractional vCISO services provide executive-level oversight to ensure strategy and governance decisions are made with a clear view of business and operational risk.

  • vCISO / Strategic Security Leadership: Fractional CISO oversight, executive advisory, board reporting, business alignment
  • Policy, Standards & Governance: Policy libraries, compliance readiness, and program documentation
  • Security Roadmapping & Budget Planning: Prioritization, tool selection, ROI alignment

Prevention & Protection

Defensible embeds proactive security into your environment as it evolves, using continuous monitoring, configuration hardening, and user education to reduce risk before attackers can exploit it.

  • Risk & Vulnerability Management : Continuous scanning, penetration testing, and threat assessments
  • Zero Trust & Network Security: Microsegmentation, device posture checks, and identity access control
  • Security Awareness & Training: Phishing simulations, behavior monitoring, and training modules
  • Integration with Managed IT / Infrastructure: Unified monitoring, patching, and configuration hardening

Detection & Response

  • Managed Detection & Response (MDR): 24/7 monitoring, alerting, triage, and response orchestration
  • Incident Response & Forensics Readiness: IR plan development, tabletop exercises, and readiness reviews
  • Incident Response (DFIR): Dedicated experts available for full forensic investigation and containment when incidents occur
