Cybersecurity Services
Cybersecurity Services for Businesses That Need Real Protection
Cyber Replay builds software securely and defends the systems you already run. We are one accountable team for both, which matters because the gap between the people who write the code and the people who defend it is where most incidents actually start.
Our pricing is published on this page. You do not need a discovery call to find out what anything costs.

Managed detection and response
Most security tooling generates alerts nobody has time to read. Managed detection and response means our security operations team owns that queue: we tune the detections, investigate what fires, and contain the things that matter, rather than forwarding you a dashboard and calling it coverage.
Coverage spans endpoints, identity and email together, because attacks do not respect those boundaries. A phishing email leads to a stolen session token, which leads to a login from an unfamiliar location, which leads to a mailbox rule quietly forwarding invoices. Watching any one of those layers alone misses the story.
What it costs
Laptop and desktop endpoint protection plus identity protection for every covered user.
Device-level detection and response without identity or user-account coverage.
Install, deploy and set up across your environment, including tuning and handover.
30-Day Deployment Guarantee. Managed detection and response is fully deployed within 30 days, or your $4,000 setup fee is refunded.
36-Month Price Lock. Your monthly rate is locked for 36 months. No renewal re-quote, and no increase as you add users inside your signed band.

Building software that is secure before it ships
Retrofitting security onto a finished application is the expensive way to do it. We build web applications, internal tools and AI features with the security work included: threat modelling at architecture, secure defaults during the build, and a full penetration test before anything reaches production.
A Secure Build is $38,000 for a custom application delivered in 90 days, penetration tested before launch. If it does not ship in 90 days we keep working at no charge until it does.
AI security
Shipping an LLM feature adds attack surface that traditional application testing does not cover. Prompt injection turns your own model into the attacker's tool. An AI agent with broad permissions becomes a privilege escalation path. A poisoned model or a compromised package in the AI supply chain reaches production the same way any other dependency does.
We test for these specifically, and we have published detailed research on agentic ransomware, prompt injection and LLM supply chain attacks.
Email security that matches how people actually work
Most business losses start in an inbox. We reduce risk from phishing, business email compromise, mailbox abuse and impersonation by combining policy hardening with monitoring and a guided response path, rather than turning filters up until legitimate mail stops arriving.
Penetration testing
A full application penetration test is $6,500 and includes a remediation-ready report plus a free verification retest once you have fixed what we found. An annual retest is $4,500. A cloud and identity hardening sprint, which covers your cloud accounts, identity provider and privileged access paths over two weeks, is $5,500.

When something is already happening
Prevention plans are useless during an active incident. If you are seeing suspicious sign-ins, fraudulent payments, ransomware behaviour or a compromised account right now, the priority is containment without destroying the evidence you will need afterwards.

How to evaluate a cybersecurity services provider
Most providers sound identical in a sales call. These questions separate them:
- Who investigates an alert at 3am? Ask for the actual escalation path and the name of the team that owns it, not a service level number.
- Does endpoint, identity and email coverage share context? Three separate tools that do not correlate will miss the chain of events that makes up a real intrusion.
- What does the reporting say? Tool output counts alerts. Useful reporting explains business risk and what changed since last month.
- Can they help during recovery, not just prevention? Plenty of providers monitor. Fewer will sit with you at hour six of a ransomware incident.
- Will they tell you the price? If the number depends on how much they think you can pay, that tells you something.

Frequently Asked Questions
What cybersecurity services does Cyber Replay offer?
Cyber Replay provides managed detection and response, security engineering, secure software development, AI and LLM security, AI integration, business automation, vibe-code security reviews, business email security, penetration testing, and incident response. Most companies start with managed security, a focused engineering project, or a penetration test based on whether the need is ongoing coverage, implementation, or point-in-time evidence.
How much do cybersecurity services cost?
Managed detection and response is $42 per user per month, or $20 per endpoint per month for device-only coverage, with a one-time $4,000 deployment fee. Penetration testing is $6,500. Secure application builds start at $9,500 for an automation sprint and $38,000 for a full custom application. Those are our standard rates and you do not need a discovery call to see them.
Who should use managed cybersecurity services?
Companies that need 24/7 protection and fast incident response but cannot justify the cost of an internal security operations centre, which realistically means several full-time analysts to cover nights and weekends. Managed services give you that coverage without the headcount.
How are cybersecurity services different from IT support?
IT support keeps systems available and productive. Cybersecurity services assume someone is actively trying to break in. The disciplines overlap but the goals differ: your IT provider restores a laptop, we work out how the attacker got onto it, what else they touched, and how to close the path.
How quickly can you deploy?
Managed detection and response is fully deployed within 30 days or the $4,000 setup fee is refunded. Penetration tests are scheduled within one to three business days of scope agreement.
Do you work alongside our existing IT provider?
Yes, and it is the common case. We handle the security function while your IT provider keeps running the environment. We define escalation paths with them at kickoff so nothing falls between the two teams during an incident.
