The District is seeking to procure a comprehensive cybersecurity solution consisting of endpoint protection, Domain Name System (DNS)-layer threat protection, and email security services to enhance its enterprise-wide defense capabilities. The endpoint protection platform must provide continuous malware detection, real-time threat response, behavioral analysis, and retrospective visibility across all managed devices. The DNS-layer security solution must inspect and filter internet-bound traffic at the DNS level, blocking access to malicious domains before threats can reach devices or users. The email security service must protect against phishing, spoofing, malware-laden attachments, and other email-borne threats, while supporting advanced spam filtering and threat intelligence integration.
