Foundational Web Infrastructure, Engineered
DNS, email, certificate management, CDN, and foundational web infrastructure engineered for reliability and security.
The Invisible Infrastructure That Everything Depends On
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.
DNS Architecture
Resilient name resolution with security built in.
DNS Resolution Path
Enterprise DNS
Authoritative DNS, recursive DNS, DNSSEC, split-horizon DNS, and geo-routing for optimal performance and resilience.
DNS Security
DNSSEC implementation, DNS filtering, DNS-based threat intelligence, and DNS tunneling detection.
DNS Resilience
Multi-provider DNS, secondary DNS, DNS failover, and redundancy architecture to prevent single points of failure.
Email Infrastructure
Deliverability, security, and architectural resilience.
Email Authentication Chain
Email Delivery
SPF, DKIM, DMARC configuration, deliverability optimization, bounce management, and reputation monitoring for reliable email delivery.
Email Security
Anti-spam, anti-phishing, attachment scanning, URL filtering, and email authentication to protect against email-based threats.
Email Architecture
Mail server design, relay configuration, archival, compliance retention, and email continuity for operational resilience.
Transactional Email
Application email integration, API-based sending, template management, delivery tracking, and webhook-based event handling.
Certificate & TLS Management
Expired certificates cause outages. Automated management prevents them.
Certificate Lifecycle
Issuance, renewal, revocation
Automated Renewal
ACME protocol, Let's Encrypt
Certificate Monitoring
Expiration alerts, inventory
TLS Configuration
Protocol versions, cipher suites
Mutual TLS
Client certificate auth
Internal PKI
Private certificate authority
CDN & Content Delivery
Global distribution with edge intelligence.
- Geographic PoD distribution
- Edge caching & invalidation
- Origin shielding
- HTTP/3 & QUIC support
- WAF integration
- DDoS mitigation
- Bot protection
- Rate limiting at edge
- Image transformation
- Format auto-detection
- Responsive delivery
- Compression strategies
CDN Architecture
Geographic distribution, edge caching, cache invalidation, origin shielding, and performance optimization.
Edge Security
WAF integration, DDoS mitigation, bot protection, rate limiting, and request filtering at the edge.
Image & Media Optimization
Automatic image transformation, format optimization, responsive delivery, and video streaming where applicable.
Web Server Infrastructure
High-performance serving with operational discipline.
Web Server Architecture
Nginx, Apache, Caddy configuration, reverse proxy design, load balancing, and high-availability web server clusters.
Application Servers
Node.js, Python, Go, and Java application server configuration, process management, and scaling architecture.
