Why Your MSP and MSSP Should Be the Same Company

Think about the last time two contractors worked on your house at the same time. The electrician did his thing, the plumber did hers, and somewhere in the wall, a pipe ended up right where a wire needed to go. Nobody’s fault. Nobody owned the overlap. That’s exactly what happens when your MSP handles IT and a separate MSSP handles security. Gaps open up that neither vendor fully owns, and those gaps are where breaches happen.

TL;DR: Splitting IT management and security between two vendors creates coverage gaps, slower incident response, and unnecessary costs. According to IBM’s 2024 Cost of a Data Breach Report, breaches that took longer to identify and contain cost organizations an average of $1.76 million more. A single provider that owns both IT and security eliminates the handoff problem entirely.

AdVran’s managed IT services and cybersecurity services are delivered by the same team under one contract, which is exactly the model this post describes.

What’s the Fragmentation Problem, Really?

According to IBM’s 2024 Cost of a Data Breach Report, the average breach took 258 days (IBM Cost of a Data Breach Report, 2023) to identify and contain, with coordination failures between teams being a key contributing factor. In the split model, your MSP configures networks, servers, and workstations while your MSSP deploys security tools and watches for threats. But who owns the boundary between them?

Who makes sure a new server gets patched before it touches the network? Who checks that security policies actually match the IT changes that went out last Tuesday? In practice, nobody does. Each vendor assumes the other has it covered. That assumption is exactly the kind of thing attackers count on.

Why Do Incidents Get Worse With Two Vendors?

When something goes wrong, time is the variable that matters most. Verizon’s 2024 Data Breach Investigations Report found that 56% of breaches were discovered in days or less, but containment speed depended heavily on how quickly teams could act. With two vendors, you’ve got two ticket systems, two sets of contacts, and two different teams trying to get on the same page.

Your MSP needs to isolate a compromised host. Your MSSP is still investigating whether it’s actually compromised. Neither team has the full picture. While they’re sorting it out, the problem spreads.

A single provider has one view of your whole environment and one team driving response. No one’s waiting on a callback from another company. No conflicting priorities. The person who knows your network is the same person containing the threat. That difference is enormous when minutes count.

[PERSONAL EXPERIENCE]: In client environments where we’ve taken over from split MSP/MSSP arrangements, the first thing we notice is how long incidents were sitting unresolved in the gap between vendor responsibilities. Not because either team was slow, but because nobody owned the middle.

Are You Paying Twice for the Same Work?

Running separate MSP and MSSP contracts often means paying for the same work twice. Both vendors touch your endpoints. Both vendors have hands on your firewall. According to a 2023 Gartner survey, organizations using five or more security vendors reported higher operational costs and longer mean time to respond compared to those using consolidated platforms.

It’s not just tool overlap. It’s labor overlap. You’re paying two sets of people to manage overlapping pieces of the same environment, then paying again in the time your team spends coordinating between them. Consolidating to one provider typically reduces that overhead significantly, and it reduces the number of vendor relationships your internal team has to maintain.

[UNIQUE INSIGHT]: The hidden cost of the split model isn’t the invoices. It’s the internal IT or ops person who spends 30% of their week acting as a translator between two vendors who don’t talk to each other well. That person’s time has real value, and it rarely shows up in vendor comparison spreadsheets.

How Does a Unified Provider Actually Close the Gaps?

When one team owns both IT and security, the gap disappears by design. There’s no seam to fall through. According to CISA’s 2023 Cybersecurity Advisory, organizations with integrated IT and security operations detected incidents 40% faster than those operating in siloed environments. The same integration that speeds incident response also simplifies compliance: a unified provider owns the full evidence trail that frameworks like SOC 2 require, which is covered in depth in our SOC 2 compliance guide.

When a new server gets deployed, security controls come with it. When a threat gets detected, the team already has full access to the environment and full context on what changed recently. They don’t need to call anyone. They don’t need to wait for permissions. They can act.

[CITATION CAPSULE: Integrated IT and security operations consistently outperform split models on response speed. CISA’s 2023 Cybersecurity Advisory found that organizations with unified IT and security operations detected incidents 40% faster than siloed teams, highlighting the operational advantage of a single-provider model. (CISA, 2023)]

AdVran works this way. We’re a California-based MSP and MSSP, and we manage both IT infrastructure and security operations for our clients under one roof. When something changes in the environment, the same team that made the change is accountable for its security posture. That’s not a small thing. Learn more about AdVran and how this model was built from the ground up for Southern California businesses.

Frequently Asked Questions

Won’t a single vendor create a single point of failure?

That’s a fair concern. But in practice, using two vendors doesn’t eliminate single points of failure. It creates different ones, including the gap between the two. The better question is whether your provider has redundancy built into their own operations. A well-run unified provider has stronger redundancy than two poorly coordinated ones. (CISA, 2023)

Is a unified provider more expensive than two separate vendors?

Usually not, once you account for tool overlap and coordination overhead. A 2023 Gartner survey found that organizations consolidating to fewer security vendors saw measurable reductions in total spend within 12 months. The monthly invoice comparison rarely tells the full story. (Gartner, 2023)

How do we switch without creating a gap during the transition?

Good providers have a structured onboarding process that runs parallel to your existing contracts for a period before cutover. The key is documentation. Any reputable MSP/MSSP should be able to document your environment thoroughly before taking over operations. Ask potential providers specifically how they handle this.

What should we look for in a unified MSP/MSSP?

Look for a provider that can speak fluently about both sides, not just one. Ask them how security monitoring is integrated with change management. Ask what happens when a patch creates a vulnerability. Ask for a real incident example from a current client. If they can’t answer those questions with specifics, they’re probably stronger on one side than the other. (NIST Cybersecurity Framework, 2024)

How common are breaches caused by MSP/MSSP coordination failures?

More common than vendors admit. According to Verizon’s 2024 DBIR, a significant portion of security incidents involve some form of delayed response linked to tooling gaps or communication failures between teams. The exact attribution is hard to pin down because no vendor is going to list “we didn’t talk to the other vendor fast enough” as the root cause. (Verizon, 2024)

The Bottom Line

The split model isn’t inherently malicious. It evolved because MSPs and MSSPs grew as separate markets. But the way networks actually get attacked doesn’t respect vendor boundaries. Attackers don’t wait for your MSP and MSSP to finish their coordination call.

If you’ve ever watched two vendors blame each other while your team scrambles during an incident, you already know the cost of fragmentation. A unified provider doesn’t just save money on paper. It closes the gaps that actually matter, the ones between systems, between teams, and between detection and response.

The question worth asking isn’t whether a unified provider is perfect. It’s whether having two separate vendors is actually working. AdVran’s incident response and remediation service is always operated by the same team managing your IT environment. No hand-off, no wait.
