This week, Forescout launched VistaroAI, and it signals a critical pivot in how we think about autonomous systems in production. Unlike the wave of general-purpose "copilots" that simply chat with your data, VistaroAI introduces agentic AI with pre-programmed security skills and human-in-the-loop control.
Plavno’s Take: What Most Teams Miss
At Plavno, we see a recurring failure pattern when teams try to build internal security agents: they wrap a generic LLM (like GPT-4 or Claude) around their SIEM API and call it a day. This is a dangerous oversimplification.
What This Means in Real Systems
Architecturally, the launch of VistaroAI validates the "Hybrid Agent" pattern we have been advocating.
- Ingestion & Normalization: Logs from endpoints, firewalls, and cloud providers are normalized.
- The Orchestrator: The LLM acts as an orchestrator, not an executor.
- The Execution Layer: The agent passes parameters to the Skill.
- Human-in-the-Loop (HITL): Execution is gated by analyst approval.
Why the Market Is Moving This Way
The market is shifting toward pre-programmed skills because the "Prompt Engineering" phase has hit a wall in enterprise security.
Business Value
MTTR Reduction: Agents can perform enrichment in seconds.
Cost Efficiency: Automating Tier 1 triage doubles throughput.
Risk Reduction: Pre‑programmed, vetted skills prevent rogue actions.
Real-World Application
1. Automated Incident Triage and Enrichment – A financial services client implements an agent that monitors their SIEM.
2. Patch Management Prioritization – An agent scans the environment for unpatched software.
3. Cloud Misconfiguration Remediation – An agent monitors AWS infrastructure.
How We Approach This at Plavno
We treat AI agents as software components that require the same rigor as a payment gateway.
First, we define the "Blast Radius." Every agent has a strictly scoped IAM role.
Second, we implement the "Plan-Review-Execute" loop.
Finally, we focus heavily on observability.
What to Do If You’re Evaluating This Now
Audit your APIs, demand skill transparency, test the "No" scenario, and build for idempotency.
Conclusion
The launch of Forescout’s VistaroAI is a clear signal that the industry is maturing past the hype of generic chatbots.
We implement similar rigorous patterns in our AI security solutions to ensure that every action can be rolled back and reviewed.
Our expertise in custom software development enables us to build the necessary integrations.
Through AI automation, we streamline repetitive tasks.
Our team also offers cybersecurity and penetration testing services.
