When Do You Need a Computer Security Consultant?

If any of these sound familiar, you're in the right place.

Your employees use personal devices and you have no control over what's installed
Ransomware hit a competitor in your industry and you're not sure you'd survive the same attack
Your servers haven't been patched in months and nobody owns the update schedule
You store customer data, financial records, or intellectual property without knowing if it's encrypted
Your WiFi network is the same one you set up three years ago with the default configuration
Former employees still have access to systems, accounts, or physical premises
You have no backup strategy — or you've never tested if your backups actually restore
Your antivirus is your only security layer and you hope it's enough
A client or insurer asked about your security posture and you couldn't answer confidently

Frequently Asked Questions About Computer Security Consulting

How much does a computer security consultant cost?
Infrastructure security assessments range from $5,000-$25,000 depending on scope. Endpoint protection and hardening starts at $3,000. Ongoing security management (Virtual CISO) starts at $3,300/month. We provide fixed-price proposals within 24 hours - no hourly billing or scope creep.
What's the difference between a computer security consultant and a cybersecurity consultant?
They're the same discipline with different terminology. Computer security is the traditional term that tends to focus on infrastructure - servers, endpoints, networks, and data protection. Cybersecurity is the modern term that also encompasses compliance, governance, risk management, and strategy. At Atlant Security, we cover both - from hands-on technical hardening to board-level security leadership.
What does a computer security assessment include?
A complete audit of your servers, workstations, laptops, mobile devices, network architecture, firewalls, wireless security, data encryption, backup systems, patch management, access controls, and endpoint protection. Every vulnerability is documented with severity ratings, and you receive a prioritized remediation plan. Delivered in 14 days.
How quickly can you secure my company's computers?
We deliver a complete infrastructure security audit in 14 days. Critical vulnerabilities are flagged immediately so you can act on day one. Most clients see measurable improvements within 30 days. Full infrastructure hardening - endpoint protection, network segmentation, encryption, patching - typically takes 60-90 days depending on environment size.
Do you support both Windows and Mac environments?
Yes. We secure Windows, macOS, and Linux environments - including mixed fleets. We also cover mobile devices (iOS and Android), cloud workstations, and BYOD policies. Our endpoint protection and hardening approach is platform-agnostic and tailored to your specific environment.
What if we already have an IT team?
Most of our clients have IT teams. We don't replace them - we augment them with specialized security expertise. Your IT team handles day-to-day operations; we handle security strategy, architecture, auditing, and incident response. We train your team, create runbooks they can follow, and provide ongoing oversight so security doesn't fall through the cracks.
