EASM security solutions evolve amid rising zero-day threats

The External Attack Surface Management (EASM) market is evolving as security teams seek to identify vulnerabilities caused by zero-day exploits. Industry comparisons show significant price variations, with factors of up to three times between providers such as Censys, Microsoft Defender EASM, and Palo Alto Cortex Xpanse.

Rather than remaining isolated products, EASM technologies are increasingly being integrated into broader platforms like Continuous Threat Exposure Management (CTEM) and existing XDR suites. Censys operates primarily as a large-scale internet scanning data layer, whereas Microsoft Defender EASM functions as a native Azure resource following the acquisition of RiskIQ.
