# AI Agent for Cybersecurity: Costs, Vendors and Containment Risks - Tool: AI Agents - Last updated: November 2026 ## TL;DR A cybersecurity AI agent triages SIEM and EDR alerts, investigates them against logs and identity data, and drafts incident reports, auto-remediating only well-understood low-risk findings: buy one like Microsoft Security Copilot (bundled into M365 E5, or $4/SCU/hour) or CrowdStrike Charlotte AI (50 free credits/month), hire an agency for non-Microsoft stacks ($15K-$30K), or pilot triage in n8n for under $70/month. Never let it isolate a host without human approval. ## What the cybersecurity agent handles (and what it shouldn't) | Task | Agent handles it? | Systems it touches | Human role | | --- | --- | --- | --- | | Alert triage and prioritization | Fully | SIEM, EDR | None for routine, low-risk alerts | | Correlating an alert with logs, endpoint and identity data | Fully | SIEM, EDR, identity provider | Reviews the investigation summary | | Known-bad file quarantine (clear signature match) | Fully | EDR | None, logged for audit | | Phishing email triage and user notification | Fully | Email security, SIEM | Reviews ambiguous cases | | Host isolation or credential revocation | With approval | EDR, identity provider | Analyst approves before the action runs | | Incident report drafting | Fully | SIEM, ticketing | Analyst reviews and finalizes | | Novel or multi-stage attack investigation | No | SIEM, EDR, identity provider | Escalates immediately to a senior analyst | | Threat-hunting hypothesis generation | With approval | SIEM, threat intel feeds | Analyst validates and investigates further | ## Frequently asked questions ### How much does an AI agent for cybersecurity cost? Microsoft Security Copilot runs $4/hour per provisioned SCU (roughly $2,920/mo) or comes bundled into M365 E5; CrowdStrike Charlotte AI includes 50 free credits/month for qualifying Falcon customers. A custom RapidDev build runs $15K-$30K upfront (up to $35K for multi-tool work), plus $150-$600/mo in model and infra costs. A DIY n8n version costs $0-$70/mo but takes your own time to build and secure. ### How long does it take to set up? A SaaS agent connected to your existing SIEM or EDR takes 2-6 weeks. A custom agency build takes 4-7 weeks because tool access has to be scoped correctly before it touches a single alert. A basic n8n version can triage alerts within 3-5 days, though a safe containment-approval flow takes 2-4 weeks. ### Can RapidDev build this for us? Yes. RapidDev has shipped 600+ apps and offers a free 30-minute consultation to scope your SIEM, EDR and which actions, if any, should run without a human approving first. ### Can an AI agent take containment actions on its own? It shouldn't, for anything irreversible. Most production deployments let the agent auto-quarantine a clear, known-bad file signature, but require human approval for host isolation, credential revocation or anything that disrupts business operations. ### What happens when the agent flags a false positive? A well-built agent scores its own confidence and escalates anything uncertain or novel to a human analyst with its full investigation attached, rather than acting on a guess. Tune alert thresholds against your own environment in the first few weeks to reduce noise. ### Can it work with Microsoft Sentinel or CrowdStrike Falcon? Microsoft Security Copilot is native to Sentinel and the broader Defender stack, CrowdStrike Charlotte AI is native to Falcon, and a custom build can connect to either plus other SIEM and EDR platforms through their APIs. ### Could the security agent itself become an attack vector? Yes, which is why OWASP's 2026 Agentic AI Top 10 lists tool misuse and identity abuse among the top agent-specific risks. Scope every tool to least privilege, treat alert and log content as untrusted input, and never give the agent standing authority over irreversible actions. --- Source: https://www.rapidevelopers.com/ai-agents/ai-agent-for-cybersecurity © RapidDev — https://www.rapidevelopers.com/ai-agents/ai-agent-for-cybersecurity
