Overview
Harmonic empowers security teams to fully understand how their organization uses GenAI, while safeguarding sensitive data from leaking into GenAI or GenAI-enabled SaaS.
Our pre-trained small language models are specialized for detecting structured and unstructured sensitive data. Harmonic then interacts with the end-user at the point of data loss, helping to avoid sensitive data leaking while coaching end users toward the secure use of AI.
With Harmonic, you can: Discover both GenAI and GenAI-enabled SaaS in use; Pinpoint use of Shadow AI and unsanctioned apps; Identify different GenAI app plans in use; Detect high-risk apps training on your data; Prevent intellectual property and sensitive data leaking into AI tools
Highlights
- Prompt-Level Visibility - Harmonic gives you clear visibility into the data employees share with GenAI tools. This includes usage across free and personal accounts, as well as prompts submitted through embedded AI features in tools like Canva, Gamma, Google Translate, and Stack Exchange.
- Real-Time Coaching at the Point of Risk - Instead of blocking GenAI tools, Harmonic intercepts prompts before sensitive data is exposed and guides users on what is risky and how to fix it. Custom small language models deliver decisions in under 200 milliseconds, and interventions can be customized with policies, role-based controls, and branded guidance to reduce friction and enable secure GenAI adoption.
- Detect High-Risk AI Usage - Harmonic continuously monitors employee use of unsanctioned GenAI and GenAI-enabled tools. It identifies when these tools train on your data, operate in high-risk regions like China, or are receiving sensitive information from employees, giving security teams the context to act quickly.

Dimensions summary
Harmonic Security Protect uses one pricing dimension: an annual price charged per user. You commit to a 12-month term and pay for each user covered. A 200-user minimum applies, so your billing starts at that user count. Costs scale directly with the number of users you enroll. The final rate depends on your specific requirements and eligibility, so you request a Private Offer for a custom quote rather than paying a fixed public rate.
Top-of-mind questions for buyers
A user is an individual employee whose AI activity the platform covers across browsers, desktop apps, and AI agents. Each enrolled person counts as one user. The 200-user minimum sets the starting billable count, so you pay for at least 200 users even with fewer people enrolled.
Cost scales directly with user count, since you pay a set rate for each enrolled user per year. Adding users raises the total proportionally. Billing never drops below the 200-user minimum. Because pricing depends on your requirements, you request a Private Offer for a rate that fits your enrolled user count.
Each user's coverage spans browsers, desktop AI apps, developer tools, and autonomous agents from one platform. Deployment runs through common device management tools on Windows, macOS, and Linux. You get an AI tool inventory on day one, with no proxy redesign or certificate setup required.

Seamless Data Security with Real-Time GenAI Risk Management
Reviewed on Aug 14, 2026
Review provided by G2
What do you like best about the product?
I really like Harmonic.Security's real-time GenAI risk visibility and pre-built compliance controls, as they make it exceptional for managing security without hindering workflows. The frictionless user experience is a standout feature because it doesn't block workflows. I also appreciate that the real-time visibility automatically flags risky GenAI prompts and the pre-built policies save time during compliance audits without impacting daily operations. The initial setup was smooth and straightforward, thanks to the seamless cloud integrations.
What do you dislike about the product?
I find the custom policy builder slightly complex for new admins, and I wish there were more detailed reporting templates for easier executive reporting.
What problems is the product solving and how is that benefiting you?
We use Harmonic.Security to prevent unsanctioned GenAI tool usage and block accidental sharing of sensitive data without hindering productivity. Its real-time visibility flags risky prompts and pre-built compliance policies save us setup time during audits, ensuring seamless daily operations.

Context-Aware Governance with Full Visibility into Shadow AI and Workflows
Reviewed on Aug 10, 2026
Review provided by G2
What do you like best about the product?
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.
What do you dislike about the product?
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.
What problems is the product 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
Reviewed on Feb 27, 2026
Review provided by G2
What do you like best about the product?
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.

What do you dislike about the product?
As a specialized solution, its reporting and dashboard customization can feel less mature than legacy platforms but it’s not a big deal.
What problems is the product 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.
