Prove It Every Day, Part 1: Why the MSP Model Is Failing FedRAMP 20x and DoW Cloud Service Providers

For years, the Managed Service Provider (MSP) model made sense. Businesses needed help managing infrastructure, networks, endpoints, cloud environments, applications, and users. Instead of building large internal IT teams, they turned to MSPs to keep everything running. As a matter of fact, I cut my teeth on this model coming up in my IT career.

Then cybersecurity became a much bigger concern, so we added another provider.

The Managed Security Service Provider (MSSP) emerged to monitor security tools, investigate alerts, manage detection technologies, and eventually provide services like Managed Detection and Response (MDR). As compliance became more complex, we added consultants, assessors, GRC platforms, vulnerability management tools, cloud security products, and continuous monitoring services.

Individually, many of these services solve legitimate problems. Collectively, however, they have created a new one: fragmentation.

Organizations now find themselves managing the companies they hired to manage their environments. The MSP manages infrastructure. The MSSP monitors security. The cloud provider operates the platform. The compliance team manages controls. The vulnerability platform identifies weaknesses. The assessor validates compliance.

Somewhere in the middle of all of this sits the Customer, trying to determine who is actually responsible when something goes wrong.

Nowhere is that more painful than for CSPs selling into the federal government. A CSP pursuing FedRAMP 20x certification or DoW CSP SRG IL authorization isn't just running a product. It's running a regulated operation that has to be secured, monitored, and proven every single day. And the clock is already running: under FedRAMP's Consolidated Rules for 2026, Vulnerability Detection and Response (VDR) and Vulnerability Evaluation and Reporting (VER) adoption is due December 7, 2026.

The problem isn't necessarily any one provider.

Security Can't Be an Add-On Anymore

The traditional MSP model was largely built around a simple idea: manage the technology first and secure it second.

Build the environment, connect the users, deploy the applications, configure the cloud, and keep everything operational. Then layer security tools, controls, and monitoring around it.

For a long time, that approach was understandable, but it still created unnecessary risk. Today, the risk is even greater because modern environments are simply too interconnected for infrastructure, security, compliance, and operations to function independently.

Consider something as routine as deploying a new cloud workload. That one decision immediately creates questions around identity and access, network architecture, logging and monitoring, encryption, vulnerability management, configuration management, data protection, incident response, and regulatory requirements.

Those aren't separate conversations anymore.

They're the same conversation.

The decision about how something is deployed affects how it can be secured. How it is secured affects how it must be monitored. How it is monitored affects how incidents are detected and investigated. And all of those decisions affect how the organization demonstrates compliance.

Trying to separate those responsibilities across multiple disconnected providers creates gaps. Those gaps create risk.

For a federal CSP, that conversation has a formal name. Under FedRAMP 20x, those questions show up as Key Security Indicators that must be persistently validated. Under the DoW Cloud Computing Security Requirements Guide (SRG), they show up as IL requirements that govern where data lives, how the environment is separated, and how it's defended. Either way, the deployment decision and the security decision are the same decision.

The MSP and MSSP Worlds Are Colliding

For years, organizations have treated IT operations and cybersecurity as separate disciplines. The MSP keeps systems running while the MSSP keeps systems secure.

But where exactly does one responsibility end and the other begin?

If a security team identifies a vulnerable system, who patches it? If the SOC detects suspicious activity caused by an overly permissive cloud configuration, who fixes the configuration? If an identity is compromised, who disables the account? If a new workload is deployed without the correct logging enabled, who owns that failure?

Under FedRAMP 20x, that first question now has a clock attached. Vulnerability detection, evaluation, and reporting run on defined timeframes, and the most serious findings can rise to the level of a reportable incident. If the team that finds the vulnerability and the team that fixes it work for different companies, the clock keeps running while they sort out who owns it.

And if a compliance requirement isn't being met because of an infrastructure configuration, is that an operations problem, a security problem, or a compliance problem?

Increasingly, the answer is all of the above.

Security operations and IT operations are converging. Cloud accelerated that convergence, and modern compliance requirements are accelerating it even further. Yet many organizations are still trying to operate these environments using service models designed when those responsibilities could be separated much more easily.

This creates another problem that doesn't receive enough attention: operational overhead.

Imagine an organization with an MSP, MSSP, cloud consultant, vulnerability management provider, compliance consultant, GRC platform, and internal IT and security teams.

Something happens.

The SOC detects suspicious activity and opens a ticket. The Customer contacts the MSP. The MSP investigates the system. Someone contacts the cloud team. The compliance team needs to determine whether the incident affects a control. Leadership wants to know what happened.

Before long, multiple teams are exchanging tickets, emails, logs, screenshots, and meeting invitations.

And worse yet, too much time has passed.

Now put that same scenario inside a DoW environment at IL4 or IL5, where the MSSP defending the mission owner's workloads depends on timely, accurate information from the CSP's own operations team. Every handoff between disconnected providers is a delay in a reporting chain the government expects to move quickly.

That's backwards.

For CSPs living under FedRAMP 20x and DoW CSP SRG IL requirements, the government has stopped asking them to describe their security once a year. It's asking them to prove it every day.

The managed services model must change with it.

In Part 2, we'll look at the model that replaces it and why FedRAMP 20x and DoW requirements already assume it. In Part 3, we'll show how we put it to work through Build, Operate, Prove, Defend. It starts with a Secure Managed Service Provider.
