MSSP, MDR and SOC as a Service are not the same. An MSSP manages your security tools and operations end to end, an MDR service focuses on actively detecting and responding to threats, and SOC as a Service gives you a complete 24/7 operations center by subscription. The right choice depends on the maturity of your security team, not the size of your company.
Below we explain each model, provide a comparison table, outline what it costs in the Mexican market and show how to decide which one fits your organization.
What is an MSSP (Managed Security Service Provider)?
An MSSP is an external provider that operates and manages your cybersecurity end to end: continuous monitoring, detection and response, vulnerability management, managed firewall and auditable evidence for compliance. Instead of building and maintaining a 24/7 in-house team, you contract the full operation as a service.
It is the broadest model: a good MSSP does not just “watch”; it integrates signals, analyzes them, prioritizes by real risk and acts, leaving an audit trail.
What Is MDR (Managed Detection and Response)?
MDR focuses on the most critical part of the cycle: detecting and containing active threats in real time. It combines behavioral analysis, proactive threat hunting and coordinated response, usually powered by artificial intelligence and machine learning to identify attacks before they cause damage.
It is ideal as reinforcement when you already have a team that manages the firewall, vulnerabilities and compliance, but you lack continuous response capability.
What is SOC as a Service (SOCaaS)?
SOC as a Service is a complete Security Operations Center run by a third party on a subscription basis: 24/7 monitoring, detection, incident analysis, threat hunting and response, all from infrastructure managed by the provider. It gives you access to the same level of technology used by large corporations and governments, without the investment of building it in-house.
The core tool of a SOC is the SIEM, which collects and correlates events to detect, analyze and remediate incidents.
Comparison table: MSSP vs. MDR vs. SOC as a Service
| Criterion | MSSP | MDR | SOC as a Service |
|---|---|---|---|
| Scope | Comprehensive security operations | Threat detection and response | Complete 24/7 operations center |
| Main focus | Tool management + operations | Hunting and containment of active threats | Comprehensive monitoring, analysis and response |
| Does it investigate and respond? | Yes, depending on the contracted scope | Yes, it is their specialty | Yes, continuously |
| Ideal for | Companies without a dedicated security team | Teams that need reinforcement in detection | Those who need enterprise capability without building their own SOC |
| Core technology | SIEM, EDR, firewall, vulnerability management | EDR/XDR + threat intelligence | SIEM/SOAR + 24/7 analysts |
Note on XDR: XDR (Extended Detection and Response) is the technology that unifies detection across endpoints, network and cloud. MSSP, MDR and SOCaaS are service models that can rely on XDR. They do not compete with each other: they complement one another.
Which one is right for your company? Quick decision guide
- No dedicated security team → Full MSSP or SOC as a Service. You need comprehensive operations from day one.
- With 1 or 2 people in security → Co-managed model: the provider runs day-to-day operations (L1/L2) and your team keeps the strategic decisions (L3).
- With a mature team (3 or more people) → MDR as reinforcement for 24/7 detection and response, while you keep full control.
- In a regulated industry (finance, healthcare, retail) or with requirements from clients/auditors → Comprehensive operations with auditable evidence is the safest option.
The question that best reveals a provider's maturity: what exactly happens if there is an incident at 3 a.m.? If the answer is “we send you an alert,” that is monitoring, not response.
How much does a managed security service cost in Mexico?
As a market reference, approximate monthly investment ranges typically fall as follows:
- Focused service (MDR + critical monitoring): from ~$2,500–$3,000 USD per month (or ~$45,000 MXN), depending on endpoints and log sources.
- Comprehensive 24/7 operations: mid five figures in USD per month.
- Enterprise (multiple sites, high complexity): $20,000–$25,000+ USD per month.
For scale: building and operating a 24/7 in-house SOC involves 8 to 12 analysts across three shifts, plus enterprise tools (SIEM, EDR, threat intelligence), which can easily cost millions per year. The managed model spreads that cost and typically comes out 60–70% cheaper for equivalent capability.
The game changer in 2026: AI on both sides
Attackers already use artificial intelligence to increase the speed and reach of their attacks. The only proportional response is a defense that is equally powered by AI: behavior-based detection, automatic event correlation and assisted containment.
At ZetTateK we build our operations, including our Agentic SOC and the AI capabilities we develop at ZetTateK AI Labs, on artificial intelligence and machine learning, precisely to reduce noise, accelerate detection and respond before an incident becomes a crisis.
Frequently asked questions
Are MDR and MSSP the same?
No. An MSSP is a comprehensive model that manages your entire security operation; MDR is a service specialized in detecting and responding to threats. Many MSSPs, such as ZetTateK, include MDR in their offering.
Can I combine an MSSP with my in-house team?
Yes. The co-managed (hybrid) model is very common: the provider runs 24/7 monitoring and initial response, and your team keeps strategy, architecture and governance.
Do I need my own SOC if I contract SOC as a Service?
No. That is precisely the goal of the model: to obtain enterprise-grade SOC capabilities without building or operating the infrastructure yourself.
What should I demand from a provider before signing?
Published SLA, auditable evidence, real response capability (not just alerts), and integration with your existing tools. Ask them to describe their process for a critical incident outside business hours.
Why does it matter that detection uses AI?
Because modern attacks use it too. AI makes it possible to analyze volumes of events that are impossible to review manually and to detect anomalous patterns in real time, reducing the time between attack and containment.
