What separates manual penetration testing from automated vulnerability scanning?

Automated scanners match known signatures against a static CVE database. They cannot reason, chain exploits, or understand business logic. Manual penetration testing by Fortress MSSP exposes chained attack vectors, authentication bypasses, privilege escalation paths, and API authorization flaws that automated tools categorically cannot find.

Can Fortress MSSP manage our entire network infrastructure?

Yes. Fortress MSSP provides full managed network infrastructure services: design, deployment, 24/7 NOC monitoring, patch management, and SLA-backed uptime guarantees. We specialize in Cisco and Meraki environments and support SD-WAN, VPN, and zero-trust network architectures.

About

The security team NYC enterprises wish they had in-house.

Years hardening NYC infrastructure

Fortress MSSP was built by engineers who were tired of watching organizations get breached by threats that were entirely preventable. We operate at the intersection of offensive security and network infrastructure — because you can't defend what you don't understand.

Every engagement is staffed by our own OSCP-certified engineers. No subcontractors. No offshore teams. Just direct accountability to the organizations that trust us with their most critical assets.

What separates manual penetration testing from a vulnerability scanner?

Vulnerability scanners match known CVEs against a static database. They cannot reason, chain exploits, or understand business logic. Manual penetration testing by OSCP-certified engineers exposes chained attack vectors, authentication bypasses, and API authorization flaws that no automated tool can find.

How long does a penetration test take, and what is delivered?

Most network engagements take 5–10 business days. A written report — executive summary, CVSS-scored findings, proof-of-concept evidence, and remediation guidance — is delivered within 72 hours of engagement close. A findings walkthrough call is included.

What is included in the final report?

Every report includes: executive summary, technical findings with CVSS scores, attack chain narratives, remediation guidance prioritized by risk, and a retest credit for critical findings. Formatted for direct submission to auditors and board-level stakeholders.

Can you manage our entire network infrastructure?

Yes. Our managed network infrastructure service includes design, deployment, and 24/7 NOC monitoring. We manage Cisco and Meraki environments with a 99.97% uptime SLA and defined SLA credits for any breach.

What compliance frameworks do you support?

We deliver technical controls and documentation for SOC 2 Type II, PCI DSS v4.0, HIPAA Technical Safeguards, NYDFS 23 NYCRR 500, and NY SHIELD Act. Our deliverables are formatted for direct submission to auditors.
