Your MSSP's Operating Model Hasn't Kept Up with Modern Threats

When did your organization last assess whether your Managed Security Service Provider's (MSSP) operating model matches your current threat landscape? Was it 2022? 2019? Never?

Most companies run security operations designed for a threat environment that no longer exists. The gap between your MSSP's delivery model and today's reality costs you visibility.

The TOM Time Warp

Most MSSP contracts were built on Target Operating Models (TOMs) designed between 2015 and 2018. Back then, threats differed. Perimeter defense was viable. Threats were largely signature-based malware with well-known fingerprints. The bad guys were loud and detectable.

Today's adversaries use your own administrative tools against you. They move through your environment with legitimate credentials. They blend into your everyday operations, so their alerts stay silent.

The question isn't whether your threats evolved (They have). The question is whether your MSSP's delivery model was developed with them in mind.

What a TOM Assessment Actually Reveals

A Target Operating Model assessment asks uncomfortable questions about how your Security Operations Center (SOC) functions versus how you think it functions.

• Alert-dependency blindness – If your entire security posture assumes threats will announce themselves, what happens when adversaries avoid triggering alerts?
• Resource allocation gaps – Most organizations find that they devote 70-80% of their SOC attention to detection and response, while they allocate less than 5% to proactive investigation. Does that ratio align with your actual risk?
• Coverage assumptions – Your MSSP contract promises "24/7 SOC monitoring and threat detection." But does it define what that means? Does it include hunting for threats that haven't generated alerts?
• Capability decay – The controls your MSSP implemented three years ago made sense then; have you validated that they still detect current attack techniques?

The Math That Should Concern You

If your MSSP's analysts spend 70% of their time triaging false positives, and their detection rules only catch known attack patterns, what are you truly protecting?

Modern breach dwell time (the time between initial compromise and detection) averages 21 days for organizations with active security programs. Your MSSP's monitoring runs 24/7 during those three weeks. Analysts investigate alerts, and your security tools generate logs, indicating that everything appears to be working.

Except that the threat that matters isn't generating any of those alerts. This isn't a technology failure. It's a gap in your MSSP's operating model, which designers built around "detect and respond," when modern security requires you to "assume breach and hunt."

Why This Assessment Never Happens

Some organizations skip TOM assessments for three common reasons:

• Nobody owns it. Your MSSP delivers to the contract. Your CISO manages board reporting and vendor relationships. Who has the mandate to step back and assess if the whole model still makes sense?
• It reveals uncomfortable truths. A thorough assessment shows that you are paying for capabilities you aren't receiving and that your current approach cannot effectively address modern threats.
• There's no trigger event. You assess the situation after a breach or audit finding puts you in crisis mode, but not in strategic planning mode.

What Changed While You Weren't Looking

Depending on when your MSSP's TOM received its design, some things have probably changed in the threat landscape:

• Attackers stopped using detectable malware. They started using PowerShell, WMI, and tools already on your systems.
• Cloud infrastructure became the norm. Your perimeter dissolved. But many Security Operations Centers still operate as if a defined edge exists to defend.
• Living-off-the-land attacks became standard. Adversaries blend into legitimate administrative activity that behavior analytics can't easily distinguish.
• Supply chain compromises became an entry vector. Threats arrive via trusted vendor credentials and legitimate software updates.

Meanwhile, many MSSP Target Operating Models remain optimized for signature detection at the network perimeter.

The Assessment You Actually Need

A meaningful TOM assessment doesn't require you to rip out your existing security stack. It requires honest evaluation:

• Coverage: What threats can your MSSP's current model detect? Can they detect credential abuse? How about lateral movement via legitimate tools or data exfiltration disguised as normal operations?
• Capacity: Where is your MSSP's analyst time going? How much is reactive versus proactive? When did they last discover a threat through investigation rather than alert response?
• Validation: How do you know you aren't currently compromised? What validates your MSSP's controls work against current attack techniques?

If you can't answer these with data, you need a TOM assessment.

What Comes Next

Understanding that your MSSP's operating model might be outdated is the first step. The more complex question is what to do about it.

The good news is that you don't need to start over. You need to complement what you have with what you are missing.

Your MSSP's 24/7 monitoring is essential. Alert-based response is critical. But if that's all your security program does, you are defending against yesterday's threats.

Next, we will examine why paying for continuous coverage might solve the wrong problem and how focused, periodic activities actually provide the best protection.
