Deloitte's Cyber Attack Surface Management

Deloitte’s Cyber Attack Surface Management (ASM) Services

Threats from threat actors are growing as business complexity and vulnerability chaos increases.

With each new IT stack component or third-party connection, an organization’s attack surface expands—introducing more potential entry points for threat actors. While many organizations have testing capabilities and security tools in place, they often lack end-to-end visibility and struggle with effective remediation due to the size and complexity of their tech environment. They do not have the unified approach to integrate key data sources, prioritize large backlogs with endless vulnerabilities, and tackle exposures in a risk-based, cost-effective manner.

Deloitte’s Cyber ASM offering forms a full-service guide for taking charge of your tech environment— from strategy to implementation to ongoing operations—so you can have peace of mind as your critical assets are protected.

Our services can be provided individually or in any combination— allowing you to address end-to-end needs for ASM. And they are all supported by our Continuous Threat Exposure Management (CTEM) programmatic approach, providing a comprehensive view of exposure.
