// Cybersecurity Services — New York City
Fortress MSSP is a New York City cybersecurity company built for financial services, healthcare, and law firms. Experienced penetration testers. 24/7 NOC. NYDFS-compliant penetration testing. No offshore triage. No junior handoffs.
// 01 — Cybersecurity Services
From 24/7 network monitoring to manual penetration testing and compliance — every service is delivered by senior engineers, not outsourced to an offshore SOC.
// 02 — Why Fortress
Most “cybersecurity companies” in NYC are IT service firms that added a firewall to their catalog. Fortress is an MSSP — security is the primary deliverable.
Every engagement is staffed by senior engineers who perform hands-on manual testing — not junior analysts running automated scanners.
Based in New York City. For internal network testing and on-site infrastructure work, our engineers deploy locally. No remote-only constraints.
Security is our primary deliverable — not IT support with a firewall in the catalog. Experienced, hands-on security practitioners.
Round-the-clock monitoring with tiered alerting. Incidents escalated and responded to before your internal team is aware of a disruption.

// 04 — FAQ
NYC businesses — especially in financial services, healthcare, and legal — face a combination of regulatory requirements and active threat actors. The most critical cybersecurity services are: (1) managed network monitoring and 24/7 SOC coverage to detect intrusions; (2) annual penetration testing to satisfy NYDFS § 500.5, SOC 2, and cyber insurance requirements; (3) MFA implementation for NYDFS § 500.12 compliance; and (4) incident response planning with defined runbooks.
Cybersecurity service costs in NYC vary by scope: managed security services for a mid-market organization (50–500 employees) typically range from $3,000–$8,000/month. One-time penetration testing engagements start at $8,000 fixed-price for a standard network or web app test. Large enterprise MSSPs (Arctic Wolf, eSentire) typically start at $15,000+/month. Fortress MSSP serves mid-market organizations with senior-engineer quality at accessible price points.
Three things: (1) senior engineers on every engagement — no junior handoffs, no offshore triage teams; (2) NYC-local, with on-site capability for internal network testing — not just remote tooling; (3) regulatory depth in New York-specific frameworks (NYDFS 23 NYCRR 500, NY SHIELD Act) that national providers lack. We are an MSSP, not an IT company that added a firewall to its catalog.
Fortress MSSP primarily serves mid-market organizations (50–1,000 employees) in regulated industries. For smaller organizations (under 50 employees) without specific regulatory requirements, we recommend starting with our fixed-price penetration testing or a cybersecurity assessment. We do not provide break/fix IT support — we are a security-focused MSSP.
Several New York regulations mandate cybersecurity controls: NYDFS 23 NYCRR Part 500 requires annual penetration testing, MFA, and risk assessment for all DFS-licensed entities. The NY SHIELD Act requires any company handling New York residents' data to maintain reasonable security controls. NYC Local Law 144 governs AI-based hiring tools. Healthcare organizations also face HIPAA Technical Safeguard requirements. Fortress MSSP's services are designed to satisfy all of these frameworks.
Yes. Fortress provides incident response retainer services and accepts emergency IR engagements. Managed services clients have 24/7 SOC coverage with pre-approved runbooks for rapid containment. For non-retainer clients, we offer emergency IR on a time-and-materials basis with a 4-hour initial response SLA. Being NYC-based means we can deploy on-site for forensic work within hours.
Yes. Fortress MSSP is headquartered in New York City. Our engineers are based in the city, which means on-site access for internal network testing, same-timezone responsiveness, and deep familiarity with New York's regulatory environment. We are not a national provider with a satellite sales office in Midtown — we are a New York company built for New York organizations.
Fortress MSSP serves financial services (hedge funds, RIAs, mortgage lenders, fintech), healthcare (medical practices, clinics, health tech), legal (law firms subject to NY cybersecurity CLE and client data obligations), and technology companies (SaaS, APIs, cloud-native). Each vertical has distinct regulatory requirements that we address with purpose-built service delivery.
