Security is not a feature you add at the end — it is a property of how infrastructure is built and operated. Hellenic Technologies takes a defence-in-depth approach to infrastructure security: multiple independent layers of controls so that no single misconfiguration or compromised component exposes client systems. This means SSL everywhere, firewalls at network and application layers, automated vulnerability scanning, regular backups with tested restores, and incident response procedures that are documented before they are needed. Our security baseline covers every client environment we manage. All traffic is encrypted in transit (HTTPS/TLS 1.2+, no HTTP). SSH access uses key-based authentication only, with access controlled via bastion hosts or VPN. Database instances are in private subnets with no public endpoints. Secrets are stored in dedicated secret management systems (AWS Secrets Manager, HashiCorp Vault) — never in environment files, repository code, or Docker images. All access is logged and monitored. Proactive security means finding vulnerabilities before attackers do. We run automated dependency scanning in CI pipelines to catch CVEs in application dependencies, OS-level package updates via unattended-upgrades, and periodic infrastructure security audits using CIS benchmarks and cloud provider security scoring tools (AWS Security Hub, Google Security Command Center, Azure Defender). Findings are triaged, prioritised, and remediated according to documented SLAs. End-to-end security services include:
  • SSL/TLS configuration and certificate lifecycle management
  • Firewall rules at network, host, and application (WAF) layers
  • SSH hardening and access control with key-only authentication
  • Secrets management via AWS Secrets Manager, Vault, or equivalent
  • Automated OS and dependency security patching
  • Daily encrypted backups with offsite storage and restore testing
  • Monitoring stack: intrusion detection, anomaly alerting, log analysis
  • Cloud security posture management with provider-native tools
  • Incident response procedures with documented severity levels and escalation
  • Annual security review and penetration testing coordination
