High Availability & DR
Built to stay up — and tested to come back
High availability and disaster recovery — clustered infrastructure, tested failover, and recovery plans with real RTO/RPO numbers behind them.
High Availability & DR services
What we deliver
Availability is architecture plus rehearsal. We design clustered, failover-ready infrastructure and — the part most organizations skip — actually test the recovery: timed failovers, documented results, and DR plans that survive contact with a real outage.
Our areas of focus include:
Cluster Design & Hardening
Hypervisor and application clustering — quorum, witness, and storage design that fails over instead of falling over.
RTO / RPO Engineering
Recovery objectives set per system with the business, then engineered and measured against — not aspirational numbers in a binder.
DR Site & Replication
Warm/cold site design, replication topology, and cloud-based DR where it beats a second data center.
Backup Integration
HA is not backup. We integrate immutable, restore-tested backups as the layer beneath failover.
Learn moreFailover Testing Program
Scheduled, timed failover exercises with documented results — evidence for auditors, insurers, and your own confidence.
Single-Point-of-Failure Audit
A systematic hunt for the one switch, cert, cable, or person your uptime secretly depends on.
Testimonials
What clients say
“Principle Security was instrumental in guiding us through our recent infrastructure and cybersecurity initiatives. Their partnership was reliable, professional, and results‑driven, which is why we continue to engage them whenever new opportunities arise.”
“Their team helped us prioritize risk without overwhelming us with jargon or checklists. Practical guidance that actually moved the needle.”
“They stepped in during a critical project and brought stability fast—tight execution, clear communication, and zero babysitting required.”
“With their managed services handling patching, backups, and detection, our internal team finally has room to focus. Reliable, low-noise, and effective.”
“We didn't need a full-time CISO—we needed experience and flexibility. Their fractional leadership model gave us exactly that.”
“Our compliance program was scattered. They brought structure, clarity, and got us aligned with FFIEC and NIST—finally audit-ready and confident.”
“Principle Security helped us redesign our entire security stack without disrupting operations. They understood our infrastructure and delivered clean, scalable solutions.”
Drive your business forward.
We focus on execution, not theory — building security and infrastructure that actually supports your business.
