Get managed security services powered by AT&T Cybersecurity

Find an MSSP now


With a major shortage of skilled resources in today’s cybersecurity market, more and more organizations are opting to outsource key security monitoring services to a managed security service provider (MSSP). Whether for log management, managed detection and response (MDR), SIEM-as-a-service, or compliance management, organizations large and small are turning to MSSPs to deliver these solutions quickly and cost-effectively.

Thousands of customers worldwide trust AT&T Cybersecurity MSSP partners to meet their security monitoring and compliance needs. Let us help you find the right MSSP to be an extension to your IT team.

Managed security offerings from a certified AT&T Cybersecurity MSSP can include:

  • Vulnerability assessment and remediation
  • Managed detection and response (MDR)
  • Threat and malware detection
  • Log management, monitoring, and archiving
  • Managed SIEM or SIEM-as-a-Service
  • Continuous compliance management
  • Cloud security monitoring and more


In a recent SANS survey, 47% of respondents indicated that a lack of trained security staff and skills were the biggest challenges when it came to threat intelligence and detection / SIEM initiatives.

What does a typical MSSP customer look like?

Limited staff

Many organizations look to MSSPs to provide their security monitoring because they do not have the security expertise or staff in-house. Building and maintaining a security monitoring infrastructure is often complex, time consuming, and requires qualified staff to assess and respond. Organizations with limited staff look to MSSPs to provide this infrastructure as a service instead of hiring in-house expertise.

Limited expertise

Many organizations do not have the in-house expertise to adequately monitor their infrastructure for threats on a regular basis. Although tools like AlienVault USM help, having the expertise to understand the threats, separate real threats from false positives, and tune the security monitoring tools as the infrastructure and threat landscape change is a value-add that MSSPs can provide. The MSSP’s security expertise becomes an extension to the customer’s existing IT security team.

Complex and expansive architectures

Not every organization has a simple, easy to monitor infrastructure. For example, organizations that require custom security deployments, either due to overly complex or expansive architecture, or very specific implementations with disparate systems can benefit greatly from the services provided by an MSSP.

Dynamic computing environments

Organizations that rely on dynamic resource allocation (for example, compute instances being generated and terminated continuously for content delivery) and require a considerable amount of automation to effectively monitor their ever-changing environments can benefit from the expertise provided by an MSSP.

Five reasons to choose a certified AT&T Cybersecurity MSSP

  • Are you considering deploying a SIEM? 
  • Do you already have a SIEM, but find it difficult to get useful, actionable data out of it?
  • Are you constrained by time, resources, or budget?
  • Do you need to fill a skills gap on your security team?
  • Are you struggling to hire or retain top IT talent with security incident response expertise?

Protection against emerging threats

Many organizations struggle to keep up with today’s rapidly evolving threat cycle. This is especially true for IT teams that are constrained by time, budget, or resources and simply do not have the capacity to constantly scour the global threat landscape for the latest attacks.

An AT&T Cybersecurity MSSP can provide a cost-effective and reliable way to protect your critical IT infrastructure against emerging threats. In addition to their own security research, AT&T Cybersecurity MSSPs continuously receive the latest threat intelligence from the AT&T Alien Labs security research team. This team constantly analyzes and validates the latest threat data, including the community-sourced, global threat data from the AT&T Alien Labs Open Threat Exchange® (OTX™). So, working with an AT&T Cybersecurity MSSP gives you multiple layers of threat intelligence.
