Modern Work Runs on AI

Employees now rely on AI tools to move faster and get more done, often long before any formal approval. This shift has changed the reality for security teams. Traditional approaches that focus on blocking only push AI use underground and create blind spots. Modern security assumes AI is part of everyday work and partners with employees to guide safe, responsible use.

To control AI use in your business, you first need clear insight into where and how it is happening. Visibility into real workflows opens the door to smarter controls, targeted education, and policies that actually work. For security teams, this is a rare moment to step ahead of a major technology change and shape how the organization adopts AI safely and confidently.

We're here to help.

Lead Your Organization Into the AI Future

A surge of AI adoption is already reshaping how work gets done. Without the right strategy, leaders face a mounting wave of compliance pressure, data privacy concerns, and frustrated teams blocked from using the tools they need. The opportunity is to get ahead of this shift by creating an AI strategy that aligns innovation with responsible use.

By understanding how AI is used across the business and pairing that insight with clear, outcome driven policies, leaders can reduce risk while enabling teams to move faster. This is a chance to turn potential disruption into an advantage.

Customer Success
"While we did understand what people were using — because we had that visibility — we didn't know how they were using it, and the data leakage was definitely a big one. ... That's when we went looking for outside help. ... It's literally hours to seconds. If we deploy a tool and it's covered by Harmonic, we have insight right away."

FAQs

Quick answers about Harmonic Security

How is this different from Zscaler or NetSkope?

Harmonic does not rely on a fixed list or single category of AI tools. It finds AI wherever it appears and evaluates the actual data being shared, delivering controls that Netskope and Zscaler cannot match.

How is the MCP Gateway deployed?

Deployment takes only minutes and can be rolled out to your entire organization through Group Policy Object, Microsoft Intune, JAMF or Kandji. The lightweight gateway requires no complex infrastructure or configuration and runs seamlessly on Windows, macOS, and Linux, providing every team with an immediate and consistent secure foundation for agentic workflows.

What is Harmonic Security's technical differentiator?

Harmonic uses purpose built small language models that understand user intent and sensitive data in milliseconds. This low latency analysis lets you enforce inline controls without slowing work down, rather than staying stuck in passive monitor mode.

How is Harmonic Security deployed?

Harmonic can be installed with a range of MDM tools, such as Kandji, Intune, or Jamf. Read more here https://docs.harmonicsecurity.app/browser-extension
