Harmonic Security is an AI Governance and Control (AIGC) platform that helps enterprise security teams manage, monitor, and enforce data protection policies across employee use of generative AI tools. Designed for organizations navigating widespread AI adoption, the platform provides real-time visibility and inline controls over what data employees share with AI applications — without blocking productivity or pushing usage underground. As employees increasingly rely on tools like ChatGPT, Claude, Perplexity, Canva AI, and other AI assistants in their daily work, sensitive data such as source code, financial projections, customer records, and confidential deal terms routinely enters these systems. Harmonic addresses this by analyzing the actual content and context of every prompt and interaction across browsers, desktop applications, and agentic workflows — including MCP servers — before data leaves the organization. The platform uses 25+ proprietary Small Language Models (SLMs) purpose-built to understand user intent and domain-specific context (such as legal discourse, M&A activity, or protected health information) with ~200ms latency, without training on customer data. This allows security teams to apply contextual, intent-aware controls rather than relying solely on keyword matching or blanket blocking policies. Harmonic Security is designed for security leaders in mid-market and enterprise organizations who need to enable AI adoption at scale without increasing data exposure risk. Customers have reported a 300% increase in AI tool usage alongside a 72% reduction in sensitive data exposure within 90 days of deployment.

"Context-Aware Governance with Full Visibility into Shadow AI and Workflows"

5/5

What do you like best about Harmonic Security?

What stands out most about harmonic security is its context aware, intent based governance that protects sensitive data without relying on rigid keywords or heavy proxies. It gives complete visibility into shadow AI, web tools, desktop apps, and agentic workflows (including MCP tool calls) across the organization while providing real-time, inline nudges that educate users without disrupting productivity. Review collected by and hosted on G2.com.

What do you dislike about Harmonic Security?

Fine-tuning custom policy rules for specialized streaming video code and OTT metadata pipelines takes a bit of extra setup time. Additionally, the executive audit dashboards could use more flexible data export options for compliance reporting. Review collected by and hosted on G2.com.

What problems is Harmonic Security solving and how is that benefiting you?

Harmonic security solves the problem of shadow AI and sensitive data leaks across browser apps, desktop tools, and developer code bases. It benefits our team by letting us safely use GenAI tools for our OTT media workflows and proprietary code without risking intellectual property or subscriber data exfiltration.

"Coach, Don’t Block: Context-Aware GenAI Security That Keeps Workflows Moving"

5/5

What do you like best about Harmonic Security?

Harmonic Security stands out for its "coach, don't block" approach, which replaces rigid security hurdles with real-time user guidance to keep workflows moving safely.

Its context-aware detection is also a major win, as it accurately identifies sensitive data within GenAI tools without the constant false positives of traditional security systems. Review collected by and hosted on G2.com.

What do you dislike about Harmonic Security?

As a specialized solution, its reporting and dashboard customization can feel less mature than legacy platforms but it’s not a big deal. Review collected by and hosted on G2.com.

What problems is Harmonic Security solving and how is that benefiting you?

Harmonic Security effectively monitors "Shadow AI" usage, identifying and securing sensitive data within unapproved GenAI tools that traditional security layers often miss.

The primary benefit is frictionless innovation, as its real-time coaching allows for the safe adoption of new AI tools without the productivity-killing "block-by-default" approach of legacy DLP. Review collected by and hosted on G2.com.
