Detect and respond to threats before they impact your business

Reduce cost and complexity

Centralized security monitoring for your critical assets across cloud environments and on premises, including endpoints, networks, and cloud apps, to help you achieve security visibility while avoiding the cost and complexity of maintaining multiple security products.

Start detecting sooner

USM delivers what you need for effective threat detection out of the box, allowing quick and broad visibility across your entire environment often within minutes of installation, so you can start detecting threats on Day One.

Stay ahead of the latest threats

Receive the latest threat intelligence automatically into the Unified Security Management (USM) platform from the AT&T Alien Labs research team, allowing you to stay up to date on emerging and evolving threats, without having to conduct your own security research.

A team you can trust

AT&T Cybersecurity has a team of skilled security professionals working with you on your security program without you having to recruit and onboard new employees. Our SOC analysts act as an extension of your in-house security team, working with your security or IT personnel to investigate and respond to security incidents, 24 x 7 x 365.

Integrate with ease

Enable AlienApps to orchestrate and automate functionality between the built-in security controls in USM Anywhere and other tools that IT security teams utilize, helping to simplify and accelerate threat detection and incident response processes.

Respond to threats faster

When a security incident occurs, the SOC analyst team works side-by-side with your incident responders to help them respond quickly and effectively, conducting in-depth incident investigations on actionable alarms and escalate incidents based on severity, in accordance with US-CERT Incident Reporting Guidelines.
