The castle-and-moat model is simple: build strong perimeter defences, trust everything inside. Firewalls, VPNs, and access controls create a protective shell, and the business assumes safety within that shell. But today’s attackers don’t always need to scale the walls. They can: Once inside, attackers move laterally, escalate privileges, and seek valuable targets like domain controllers, email servers, and customer data.

Cybercriminals have changed tactics. Credential phishing has overtaken ransomware as the most common way to breach enterprise networks. What started as amateur email scams is now an industrial operation with nation-state precision. Phishing campaigns today mimic real user behavior so well that even trained employees fall for fake login pages, social engineering calls, and credential traps. If attackers get credentials, they skip the noise and walk right through the digital front door.

Enterprise-wide deployment of Keeper isn’t just a best practice – it’s a necessity. Stolen credentials fuel everything from phishing attacks to full-blown breaches. Verizon’s 2025 Data Breach Investigations Report identifies the top three methods of unauthorized access as stolen credentials, phishing and vulnerability exploits, all of which are closely tied to identity.

Let’s get this out of the way: the term vulnerability management has always been misleading. It evokes the idea that we’re wrangling a tidy list of software flaws, checking boxes, patching holes, and keeping things humming. But anyone who’s worked in the trenches or tried to explain this chaos to an executive board knows the truth. What we call “vulnerability management” isn’t a single discipline, or even a well-contained function.

Managing cybersecurity as a managed service provider isn’t getting any easier. You’re juggling a fast-evolving threat landscape, rising customer expectations, and fierce competition ‒ all while trying to grow your business and protect your clients. Even the most experienced MSPs can fall into common traps that drain profits, overcomplicate operations, and increase security risk. Here are five pitfalls that might be holding your business back ‒ and how to sidestep them.
