DNS, email, certificate management, CDN, and foundational web infrastructure engineered for reliability and security.
When DNS fails, nothing works. When certificates expire, trust breaks. When email delivery fails, communication stops.
Web services are the foundational layer that every application, website, and communication system depends upon. HRHK engineers these services for reliability, security, and operational resilience—because when foundational infrastructure fails, the impact cascades across your entire technology ecosystem.
Resilient name resolution with security built in.
Authoritative DNS, recursive DNS, DNSSEC, split-horizon DNS, and geo-routing for optimal performance and resilience.
DNSSEC implementation, DNS filtering, DNS-based threat intelligence, and DNS tunneling detection.
Multi-provider DNS, secondary DNS, DNS failover, and redundancy architecture to prevent single points of failure.
Deliverability, security, and architectural resilience.
SPF, DKIM, DMARC configuration, deliverability optimization, bounce management, and reputation monitoring for reliable email delivery.
Anti-spam, anti-phishing, attachment scanning, URL filtering, and email authentication to protect against email-based threats.
Mail server design, relay configuration, archival, compliance retention, and email continuity for operational resilience.
Application email integration, API-based sending, template management, delivery tracking, and webhook-based event handling.
Expired certificates cause outages. Automated management prevents them.
