Network Penetration Testing for IT Managed Services Providers (MSPs) companies in St. Louis (MO)
Network Penetration Testing for IT Managed Services Providers (MSPs) in St. Louis, MO
IT Managed Services Providers in St. Louis and across Missouri sit on a prime target: your clients’ networks, data, and remote access tools. Threat actors know that compromising one MSP can open doors into dozens of customer environments across the region. Ransomware crews, phishing campaigns, credential stuffing, and targeted attacks on remote management tools (RMM, VPNs, firewalls) are all routinely used to gain a foothold in MSP-managed networks.
The financial impact of a successful breach is substantial. In 2021, the median reported cost of a data breach reached $4.24M—and that number doesn’t include many incidents that never make it into public statistics. For an MSP, a single compromise can quickly become a business continuity and reputational crisis affecting every client you serve in the St. Louis metro area and beyond.
To stay ahead of these threats, MSPs need regular, independent security testing to confirm that existing controls, configurations, and processes actually work under real-world attack conditions—not just on paper.
What Is Network Penetration Testing for MSPs?
Network penetration testing (net-pen testing) is a controlled, ethical hacking exercise where security professionals simulate attacks against your MSP infrastructure and client-facing services. This typically includes:
External attack surface – firewalls, VPNs, client portals, RMM tools, cloud services, and exposed applications used to manage customer environments.
Internal MSP network – domain controllers, file servers, backup systems, and management platforms that could be leveraged for lateral movement into client networks.
Access and privilege models – how technician accounts, service accounts, and remote access are configured and monitored.
For MSP leaders, the value is straightforward. A well-run penetration test provides:
Clear visibility into vulnerabilities in your MSP operations and managed client environments.
Evidence of how far an attacker could go with a single compromised credential, phishing success, or misconfigured system.
Support for compliance with regulatory requirements and customer security expectations (HIPAA, PCI, GLBA, SOC 2, cyber insurance, and large enterprise vendor assessments).
Missouri Network Penetration Testing Experience
OCD Tech provides network penetration testing services tailored to MSPs in St. Louis and throughout Missouri. We work with IT Managed Services Providers that support:
Healthcare practices and hospital systems
Financial services and community banks
Manufacturing and logistics operations along the I‑70 and I‑64 corridors
Local government, education, and professional services firms
Our team combines IT risk advisory, configuration review, and hands-on offensive security experience. That means we don’t just run tools and hand you a report—we show you how an attacker would actually move through your MSP environment and into client networks, then provide prioritized, practical remediation steps your technical team can realistically implement.
The result is a penetration test that not only highlights weaknesses, but also helps you:
Harden RMM and remote access used to manage client systems.
Reduce insider threat and assumed compromise risk through better segmentation and privilege controls.
Strengthen your security offering and demonstrate due diligence to existing and prospective customers in the St. Louis region.
Our Network Penetration Testing Methodology
OCD Tech follows a structured, repeatable penetration testing methodology aligned with industry best practices (including elements of Red Team and assumed compromise testing). For MSPs, we focus on both your core infrastructure and the pathways into client environments. Typical phases include:
Passive Reconnaissance – Quietly mapping your public-facing footprint, domains, IP ranges, and exposed services without direct interaction where possible.
Active Reconnaissance – Safely probing live systems to identify open ports, services, and misconfigurations that could be used as entry points.
Social Engineering (where in scope) – Testing how well your team detects and responds to phishing, vishing, or pretexting that targets MSP help desks and technicians.
Exploitation – Attempting to exploit identified vulnerabilities (e.g., weak passwords, missing patches, insecure RMM or VPN setups) to gain initial access.
Post-Exploitation – Assessing what an attacker can access after the first foothold: sensitive data, backup systems, administrative consoles, or client connections.
Privilege Escalation – Attempting to gain higher-level permissions, such as domain admin or access to core MSP management platforms.
Lateral Movement – Testing how easily an attacker can move across your internal network and, where in scope, into linked customer environments.
Maintaining Access – Demonstrating how persistent access could be established if your monitoring and detection controls fail.
Covering Tracks – Evaluating logging and monitoring by simulating how an attacker might attempt to evade detection.
Reporting & Executive Debrief – Delivering a clear, prioritized report, including risk ratings, evidence, and remediation guidance for both technical teams and non-technical leadership.
Throughout the engagement, we coordinate closely with your leadership and technical staff to ensure testing is controlled, safe, and aligned with business operations. When appropriate, we can also work in a more collaborative Purple Team style with your internal or outsourced Blue Team to improve detection and response capabilities in real time.
National Reach with Local Focus
While we work extensively with MSPs in St. Louis and across Missouri, OCD Tech also delivers network penetration testing and IT security assessments nationwide, including:
Regardless of location, our approach remains consistent: realistic attack simulation, clear reporting, and pragmatic remediation guidance designed for MSPs that manage critical infrastructure for others.
