Security EA 3.0 Cisco Secure Access DNS Essentials | DNS Security — E3S-SA-DNSE

Move threat prevention closer to the request itself. Security EA 3.0 Cisco Secure Access DNS Essentials provides a licensing path for DNS-layer security within Cisco Secure Access, helping organizations stop access to known malicious destinations before traffic progresses deeper into the stack. This offering is built for enterprise teams that need predictable licensing under Cisco’s EA 3.0 framework. It supports procurement standardization while giving security architects a cloud-delivered control point for users working from offices, homes, and third-party networks. DNS security is valuable because it reduces attack surface early. By filtering suspicious lookups and enforcing policy at the resolver layer, teams can cut down on phiJTFng exposure, malware callbacks, and unnecessary downstream inspection load. For organizations comparing point solutions, the advantage is architectural consistency: a Cisco subscription aligned to enterprise buying, centralized administration, and security coverage that follows the user rather than the network perimeter.
