RHEL & Unix services
Expert RHEL and Unix systems engineering for the services that define an ISP or MSSP footprint: DNS, DHCP, mail, SNMP monitoring, RADIUS, and network policy control planes.
MSSP · ISP · Critical Infrastructure
Systems that stay online. Edges that stay hard.
Avalon Wave Software is an infrastructure and security consultancy for general internet services— especially MSSP and ISP operations. We design, harden, and operate the stack that keeps networks, mail, identity, and compute trustworthy under real load.
Mission
Internet operations with an operator’s discipline
From edge routing and mail infrastructure to hypervisor estates and Windows identity, Avalon Wave bridges deep systems engineering with security analysis. We treat uptime, observability, and compliance as one design problem—not three afterthoughts.
Expertise
Capabilities that map to real networks
Five domains. One standard: production-grade engineering for services people depend on every day.
Hypervisor infrastructure
Design and operations across Proxmox, VMware, KVM/QEMU, and Hyper-V—clusters, storage, live migration strategy, and capacity planning that survives growth and failure.
Enterprise networking
Hands-on depth with Cisco and Arista platforms—routing, switching, segmentation, and the policies that keep multi-tenant and multi-site environments coherent.
Windows, identity & collaboration
Windows Server estates, Active Directory, Exchange, and Microsoft 365—hybrid identity, messaging continuity, and the operational glue between cloud and on-prem.
Security analysis & hardening
Internet security expertise with CompTIA-aligned foundations. Security analysis and server system hardening aligned to Center for Internet Security benchmarks and FIPS 140-3 expectations.

Security & compliance
Harden first. Prove it. Keep it that way.
Security is not a slide deck—it is configuration, evidence, and continuous discipline. We specialize in analysis and hardening that stands up to operational reality.
- Baseline and remediate systems against Center for Internet Security (CIS) guidance.
- Align cryptographic and module choices with FIPS 140-3 oriented deployments.
- Threat-aware review of edge services: mail, auth, DNS, remote access, and admin paths.
- Documented hardening patterns you can audit, automate, and hand to the next on-call.
CIS-aligned hardening
Benchmarks translated into enforceable, reviewable system state.
FIPS 140-3 focus
Cryptography and module posture for regulated and high-assurance environments.
CompTIA-aligned expertise
Security fundamentals grounded in practical internet and server defense.
