MSP vs MSSP: Which One Does Your NYC Business Need?
An MSP (managed service provider) runs and supports your IT: computers, network, email, backups, and the help desk your staff calls. An MSSP (managed security service provider) focuses specifically on security: monitoring for threats, investigating alerts, and helping you respond. That is the short version of MSP vs MSSP. The longer version matters, because many providers now blur the line, and a New York small business choosing between them needs to know what it is actually buying.
MicroSky Managed Services has supported NYC businesses since 2015 as an MSP with a security practice, so we see this question from both sides. Here is a straight comparison.
MSP vs MSSP: the core difference
The simplest way to think about it: an MSP keeps your technology running, and an MSSP keeps your technology watched.
If you want the full background on the first half of that comparison, start with our guides What Is an MSP? and What Does an MSP Do?. In short, an MSP takes ongoing responsibility for day-to-day IT operations for a predictable monthly fee.
An MSSP, by contrast, is built around outsourced security monitoring and management. Typical MSSP services include security monitoring through a security operations center (SOC), log collection and analysis in a SIEM, managed firewall and intrusion detection, managed endpoint detection and response, vulnerability scanning, and incident response support. The emphasis is on watching for and handling security events, not resetting passwords or setting up printers.
Put another way, if your internet goes down at 9 a.m., you call your MSP. If someone signs into your bookkeeper’s Microsoft 365 account from overseas at 3 a.m., the MSSP’s monitoring is what should notice it. Both jobs matter. They just require different tools, different skills, and different ways of working with your team, which is why it pays to be precise about which one a proposal actually covers.
Side-by-side comparison
| Area | MSP | MSSP |
|---|---|---|
| Primary goal | Keep IT working and users productive | Detect, investigate, and help contain threats |
| Typical services | Help desk, patching, device management, backups, network, Microsoft 365 or Google Workspace administration, vendor management, IT planning | Security monitoring, SIEM, managed EDR, threat investigation, vulnerability management, incident response support, security reporting |
| Who calls them | Your employees, when something is broken or needs setting up | Usually the provider calls you, when something suspicious is found |
| Main metric | Uptime, ticket response, user satisfaction | Time to detect and contain, alert quality |
| Staff skill set | Systems administrators, help desk technicians, network engineers | Security analysts, incident responders, threat hunters |
| Fixes the problem? | Usually yes, hands-on in your environment | Often recommends or coordinates fixes; may rely on your MSP or IT staff to make changes |
That last row is the one people miss. Some MSSPs are strictly monitoring and advisory. When they find a compromised server, they tell you, and someone else has to rebuild it. Ask exactly where the provider’s responsibility stops.
Where the line is blurring
Ten years ago, many MSPs handled antivirus and a firewall and called it security. That is no longer enough. Attackers have gone after MSPs directly because one provider can open the door to many customers. In 2022, CISA, the NSA, the FBI, and partner agencies in the UK, Australia, Canada, and New Zealand issued a joint advisory, Protecting Against Cyber Threats to Managed Service Providers and their Customers, laying out baseline security practices for both MSPs and their clients, including MFA, logging, and segregating internal networks.
As a result, many MSPs have added security services such as EDR, managed SOC, and email security, while some MSSPs have added more hands-on remediation. Today you will find:
- Traditional MSPs that handle IT operations and basic security tools, without dedicated security monitoring.
- Security-focused MSPs that run IT operations and offer layered security services like EDR and SOC monitoring.
- Pure-play MSSPs that only do security, often alongside your existing MSP or internal IT team.
Labels on a website matter less than the service list and the contract.
Which one does your business need?
An MSP is usually the right starting point if
- You do not have reliable IT operations yet: patching is spotty, backups are untested, or nobody owns onboarding and offboarding.
- Your staff needs a help desk to call.
- You want one partner to handle day-to-day IT, vendors, and planning.
Security monitoring on top of a messy environment produces a lot of alerts and little progress. Basic IT hygiene comes first.
An MSSP or added security services make sense if
- You handle sensitive or regulated data, such as financial, legal, or health records.
- A cyber insurer, client, or regulator is asking about monitoring, logging, or incident response.
- You already have solid IT operations, in-house or through an MSP, and need dedicated eyes on threats.
Many businesses need both
The common answer for growing NYC firms is an MSP for operations plus security monitoring, either from the same provider or from a separate MSSP that works alongside it. If you use two providers, make sure they have a written handoff: who watches, who fixes, and who calls you.
Questions to ask any provider
- What exactly is included in monitoring, and which systems are covered: endpoints, Microsoft 365 or Google Workspace, firewalls, servers?
- Who reviews alerts, and what happens after business hours?
- When you find something, do you fix it, or do you hand it to us or another vendor?
- How do you secure your own remote access tools and admin accounts? (Given the CISA advisory above, this is a fair question for any provider.)
- What reporting will we receive, and how often?
- What does onboarding look like, and what do you need from us?
- If we leave, how do we get our data, logs, and admin credentials back?
How MicroSky fits
MicroSky is an MSP first. We run managed IT for NYC businesses, including help desk support, monitoring, and backup. On the security side, our cyber security services include endpoint detection and response, a Managed SOC focused on visibility, triage, and response guidance, and email security. For businesses with their own IT staff, we also offer co-managed IT. Our support desk is staffed Monday through Friday, 8 AM to 6 PM ET, with after-hours on-call support.
That combination means one team can both spot a problem and fix it, which removes the most common gap in the MSP-plus-MSSP setup. It is not the only good model, but it is the one we know works for many small and mid-sized offices.
Frequently asked questions
Is an MSSP more expensive than an MSP?
Pricing varies widely by scope, number of users and devices, and the systems monitored, so there is no universal answer. Compare proposals on what is covered and who does the remediation, not just the monthly number.
Can an MSP also be an MSSP?
Yes. Many MSPs offer security monitoring and response. Check whether they have dedicated security tooling and processes, such as EDR, SOC monitoring, and documented escalation, rather than just reselling antivirus.
Do I still need an MSP if I hire an MSSP?
Usually, unless you have internal IT staff. An MSSP watches for threats; someone still has to patch systems, manage users, and fix what breaks.
What is a SOC, and how does it relate to an MSSP?
A SOC, or security operations center, is the team and process that monitors and responds to security events. Many MSSPs deliver their services through a SOC. Some MSPs run or partner with one too.
