If you have started shopping for outside IT help, you have probably run into two acronyms that look almost identical: MSP and MSSP. One letter apart, and a lot of providers use them loosely, so it is easy to assume they are the same thing. They are not. The difference comes down to one word, security, and getting it wrong leaves a gap that is expensive to discover the hard way.
Here is what each one does, why most businesses actually need both, and how to avoid the trap that catches companies who only buy one.
What an MSP does
A Managed Service Provider keeps your technology running. This is the day-to-day backbone of your IT:
- Helpdesk and user support
- Managing and patching laptops, desktops, and servers
- Administering Microsoft 365, email, and cloud apps
- Network and Wi-Fi management
- Backup and recovery
- Procurement, onboarding and offboarding, and general IT strategy
The goal of an MSP is uptime and productivity. When something breaks, they fix it. When you hire someone, they get a working laptop and the right access. A good MSP makes your technology boring in the best way, which is to say it just works.
What an MSP is not, by default, is a security operation. Patching and basic protection help, but keeping software updated is not the same as actively hunting for threats, watching your environment around the clock, and responding to an attack in progress.
What an MSSP does
A Managed Security Service Provider keeps you protected. Their focus is threats, not tickets:
- A Security Operations Center, or SOC, monitoring your environment 24/7
- Threat detection and active response
- Endpoint detection and response, or EDR, and managed detection and response, or MDR
- Log and event monitoring
- Vulnerability management and testing
- Incident response when something gets through
- Aligning your environment to security frameworks
The goal of an MSSP is to find and stop attacks, ideally before they cause damage, and to contain them fast when they do. An MSSP assumes someone is trying to get in, because someone always is.
What a pure MSSP usually does not do is run your everyday IT. They are not going to set up your new hire’s laptop or troubleshoot why the printer is offline.
The gap most businesses fall into
Here is where it gets expensive. Many businesses buy one and assume it covers the other.
If you only have an MSP, your technology runs smoothly but your security is thin. There is no one watching for an intrusion at 2 a.m., no active response, and patching alone will not stop a determined attacker or a compromised email account. You feel covered because everything works, right up until it does not.
If you only have an MSSP, you have strong security but no one running your daily operations, so you still need an MSP. Now you are coordinating two separate vendors. And when something goes wrong, you get the worst outcome in IT: finger-pointing. The MSP says it is a security issue, the MSSP says it is a configuration issue, and you are stuck in the middle while the problem sits unsolved. The seam between two vendors is exactly where real incidents slip through, because neither one fully owns the whole picture.
For most small and midsize businesses, the honest answer to “which do you need” is both. The real question is whether you get them as two vendors bolted together, or as one team that was built to do both.
Why CyberDuo is different: we are both, by design
This is the gap we were built to close. CyberDuo is a cybersecurity-led MSP with our own in-house Security Operations Center. We are not an IT shop that added a security product to the menu, and we are not a security firm that cannot run your help desk. We do both, under one roof, with one team accountable for all of it.
A few things set that apart from most providers you will compare us to:
Our SOC is in-house, not outsourced. This is the big one. Many providers who advertise security quietly resell a white-labeled SOC run by someone else. Ours is staffed by our own team. That means faster response, real context about your environment, and one group that owns both the alert and the fix.
Security is our DNA, not an add-on. We have operated as a security-focused provider since 2005. Every decision, from how we set up a new client to how we manage Microsoft 365, starts from a security posture rather than tacking it on at the end.
Credentials that back it up. We are SOC 2 Type II attested, our work is led by CISSP-certified expertise, and we are a Microsoft Solutions Partner. For regulated clients, we align your environment to frameworks like CMMC and NIST 800-171 on the technical side.
A modern, serious security stack. We run tools like SentinelOne for endpoint detection and response, Blackpoint for managed detection and response, KnowBe4 for security awareness training, and Horizon3.ai NodeZero for continuous security testing, all managed by our SOC. This is enterprise-grade tooling delivered at a small and midsize business scale.
One vendor, no seam. Because your IT and your security live with the same team, there is no finger-pointing and no gap between the people who keep you running and the people who keep you safe. Decisions get made with both goals in view at once.
We focus on regulated and security-conscious businesses, including law firms, medical practices, financial services companies, and manufacturers, where both uptime and protection are non-negotiable. If that sounds like you, our cybersecurity services and managed IT services are designed to work as one.
So which do you need?
If you are a typical small or midsize business, you need MSP capabilities and MSSP capabilities. You can assemble that from two vendors and manage the overhead and the finger-pointing, or you can get both from one provider that was built to deliver them together.
If you would rather have one team own your technology and your security, and you run businesses across Orange County or greater Southern California, reach out. We will look at what you have today, show you where the gaps are, and give you one straight plan that covers both.
