Security is a top priority for managed service providers (MSPs) overseeing complex environments for their clients. One of the most underestimated vulnerabilities in these environments is the use of third-party tools that rely on agents installed on servers or end-user devices.
How third-party agents expose MSPs to unnecessary risks
Third-party platforms often require the use of agents installed directly on client systems. These agents, while critical to the operation of the software, can become entry points for attackers if they’re not regularly updated, patched, or properly configured. The problem only gets worse when agents rely on insecure practices, such as hardcoded credentials or outdated security protocols.
The issue with third-party agents is threefold:
- They increase the attack surface: Every agent running on a server or endpoint becomes another possible way in for attackers. If an agent is vulnerable, the whole environment can be compromised.
- They require constant maintenance: Keeping agents secure requires frequent updates and patches, but even the most diligent MSPs can fall behind. A delayed patch or missed update can leave systems open to exploitation.
- You’re relying on someone else’s security posture: Relying on a third-party agent means you’re handing over a huge amount of trust to someone else, with little control over whether or not they make costly mistakes.
Recent incidents highlight security risks
The recent SolarWinds Web Help Desk (WHD) breach is a prime example of how agent-based systems can introduce risks that leave organizations vulnerable.
The recent flaw discovered in SolarWinds WHD. In October 2024, allowed attackers to exploit hardcoded credentials (CVE-2024-28987) to access WHD endpoints, potentially allowing unauthorized users to modify data or access sensitive information. This incident serves as a reminder of the dangers inherent in using third-party software with vulnerable agents.
While SolarWinds released a hotfix to address the issue, the security risk was introduced by an agent-based tool. For MSPs, relying on these platforms means exposing your clients to potential breaches that could otherwise be avoided.
Why native Microsoft tools offer a safer alternative
Unlike many third-party solutions, native Microsoft tools are designed with an agent-free architecture. This minimizes the attack surface, providing MSPs with a more secure way to manage environments. Here’s why native Microsoft tools stand out:
No need for agents
Microsoft’s native tools—such as Microsoft Defender, Azure Virtual Desktop (AVD), and Microsoft Intune—are cloud-based and don’t rely on agents installed on end-user devices or servers. By eliminating the need for agents, MSPs can avoid many of the vulnerabilities that come with agent-based platforms.
Simplified updates and patching
Microsoft consistently delivers security patches and updates (Patch Tuesday). This regular cadence of updates ensures that systems remain secure without requiring manual intervention from MSPs. A recent example is the swift resolution of the Windows Kernel TOCTOU vulnerability (CVE-2024-30088), which was patched before widespread exploitation could occur.
Secure identity management
With tools, such as Azure Active Directory, Microsoft enables password-free authentication methods, eliminating one of the major vulnerabilities often found in agent-based tools: hardcoded credentials. By leveraging secure identity management practices, MSPs can ensure that their client environments are protected from unauthorized access.
The path to stronger security for MSPs
The SolarWinds WHD incident is just one of many incidents that illustrate the dangers of relying on agent-based tools. For MSPs, the lesson is clear.
Reducing your reliance on agents can significantly lower the risk of a security breach. By choosing native solutions, such as Microsoft’s cloud-based tools, you can offer your clients a higher level of security while simplifying management tasks.
