Deployed on AWS
Harmonic Security lets your teams adopt AI tools safely by protecting sensitive data in real time with minimal effort. It gives you full control and stops leaks so your teams can innovate confidently.
4.6
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 Explore it provides CISOs, CIOs, and AI leaders the visibility they need to make effective AI governance and investment decisions.
Deploy the Harmonic browser extension, and within days you will have a complete map of the AI tools your workforce actually uses, the data flowing into them, and the business outcomes employees are getting in return. You can also gain the same insights into desktop AI usage via OpenTelemetry data from compatible applications (including Claude Cowork and ChatGPT Codex).
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
This listing has one pricing dimension: an annual price charged per user. You pay for each user, per year, and a 200-user minimum applies. Your total scales with the number of users you cover. The price depends on your specific requirements and eligibility, so you request a Private Offer for a custom quote rather than paying a fixed published rate.
Top-of-mind questions for buyers
One user is one employee whose AI activity the platform monitors through the browser extension or desktop telemetry. You are billed per covered employee. Certain groups, such as HR, Finance, Ops, and Founders, are excluded from reporting by design, and employee names can be masked in the portal.
No. Your cost is driven only by user count, not by how many AI tools you discover. Explore maps tools across your workforce, including embedded and unsanctioned apps, without adding per-application charges. Adding or removing monitored tools does not change your bill.
Your total scales with the number of covered users, and a 200-user minimum applies. Below that count, you still pay for 200 users. Pricing depends on your specific requirements and eligibility, so request a Private Offer to confirm how added users affect your quote.

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.
