As a Managed Service Provider (MSP), vCISO, or IT reseller, your clients count on you to keep them safe. But the cybersecurity world can be a mess of high prices, slow service, and weak testing methods. Penetration testing, also called a pentest or a pen test, is how you find and fix security holes before bad actors do. This isn't just about running a scanner; it's about showing real value and helping clients meet rules like SOC 2, HIPAA, and PCI DSS.
Offering affordable, fast, and manual penetration testing makes your business stand out. We're a channel-only partner, meaning we only work with you and never go after your clients. This guide covers the 3 types of penetration testing every MSP and vCISO should know. We'll explain how each pen test works and how you can offer it as a white label pentesting service to grow your business and become a trusted advisor.
What Is External Network Penetration Testing?
External network penetration testing is your first line of defense. It's like having a security pro check all the doors and windows of your client's business from the outside. This type of pen test focuses only on things connected to the internet, like servers and cloud services. The goal is simple: find and fix security weaknesses before a real attacker does.
Our process starts by mapping out your client’s internet footprint. We find everything from web servers to VPNs. Then, our certified pentesters (with certifications like OSCP, CEH, and CREST) manually try to break in. This hands-on, manual pentesting is so important because automated scanners miss the tricky stuff and can give you a bunch of false alarms, wasting your time.
An external pen test often finds big risks that could cause a major data breach. Common findings include exposed login portals, unpatched servers, and leaky cloud storage. As your white label pentesting partner, we give you a clear report you can brand as your own. This helps you show immediate value and gets your clients ready for compliance audits like SOC 2 and PCI DSS.
What Is Internal Network Penetration Testing?
An internal network penetration testing engagement shows what happens if an attacker is already inside. This could be a disgruntled employee or someone who stole a password. This pentest checks the internal network to see if an intruder can move around freely and access sensitive data. It answers the question: how bad could a breach get?
We start this penetration test with basic employee-level access. From there, our certified pentesters (with OSCP and CREST certifications) look for ways to gain more power. This manual pentesting is key to finding weak spots in Active Directory or network setups that scanners miss. The main goal is to see if we can become a Domain Admin, showing the full potential impact of an insider threat.
Internal pen testing often finds problems that could turn a small issue into a disaster. We frequently find weak server configurations, flat networks with no security zones, and outdated internal systems. For an MSP or GRC company, fixing these issues is crucial for protecting clients and meeting compliance rules like ISO 27001 and HIPAA. We provide a fast, detailed report with a clear fix-it plan, making you the hero.
What Is Web Application Penetration Testing?
Web application penetration testing focuses on custom software and APIs, which are the engines of modern business. Unlike a network pen test, this looks for flaws inside the code of a customer portal or SaaS platform. Think of it as a deep inspection of an application’s internal wiring to find hidden dangers that could lead to a data breach.
Our approach uses a mix of automated tools and deep manual pentesting by our certified experts (OSCP, CEH). We follow guidelines like the OWASP Top 10 to find common but critical bugs. This hands-on work is vital because automated tools don’t understand business logic. They can’t spot flaws where an attacker could access another user’s account just by changing a number in the web address.
A web application pen test often finds serious risks like SQL injection, which could let an attacker dump an entire database. Other common issues include broken authentication that allows account takeovers. As your white label pentesting partner, we provide a report with code-level examples for developers to fix things fast. This helps your MSP secure your client's most valuable assets and meet strict compliance rules for PCI DSS and SOC 2.
Choose the Right Partner for Your Pentesting Needs
We’ve covered the core types of security assessments: external, internal, and application penetration testing.
