In short: DefensX Nexi AI is an AI agent built on the DefensX secure browser. It turns browser activity, login telemetry, file flows and AI prompts into plain-English answers, dashboards and scheduled reports on productivity, AI adoption and risk. It is licensed per user and works only alongside DefensX browser security.
What Nexi AI is
Nexi AI is an AI agent from DefensX that runs on the DefensX browser security platform. DefensX already sees what happens in the browser in order to protect it. Nexi uses that same data to answer business questions, rather than leaving it in security logs that only an administrator reads.
Instead of building reports by hand, a manager can ask Nexi a question in plain English. Answers come back as real-time chat responses, on dashboards, and as weekly PDF reports and scheduled digests. DefensX also offers a chat interface through everyday messaging apps such as WhatsApp and iMessage, so leaders can ask a question from their phone.
DefensX describes Nexi as one-click to activate for organisations already running its secure browser, with no separate integration project.
What data Nexi AI uses, and the guardrails
Nexi AI works from telemetry the DefensX secure browser already collects:
- Browsing activity: the sites and web applications used, page titles and time spent
- Login telemetry: which business applications people sign in to
- File flows through the browser
- AI prompt stream: what is sent to, and returned from, AI tools
DefensX states that this data is inspected and stored inside its secured browser container, that the organisation grants scope-limited access, that prompts and responses are encrypted at rest, and that customer data is used for inference only and never to train external language models. It also states that Nexi inspects requests to AI tools in the browser and redacts personal data and source code before they leave.
What Nexi AI reports on
| Area | Examples of what you can see |
|---|---|
| Productivity | Productivity dashboards and time-on-task heat maps by team |
| AI adoption | Which AI tools are used, and a baseline of AI adoption across the business |
| Company data Q&A | Plain-English answers to questions about how work gets done |
| Return on investment | ROI projections, including software licence costs that could be avoided |
| Risk and compliance | Outputs that can be mapped to audit evidence for frameworks such as SOC 2, GDPR and NIS2 |
This makes Nexi relevant to three audiences: leadership wanting a view of how work is done, HR and operations looking at workload and adoption, and security and compliance teams who need evidence of how data and AI tools are being used.

Employee monitoring and UK GDPR
Because Nexi AI reports on how people work, it counts as monitoring workers under UK data protection law. Before switching it on, UK organisations should be clear about the purpose, tell staff what is collected and why, and keep what is reported proportionate to that purpose. The Information Commissioner's Office guidance on monitoring workers expects a data protection impact assessment where monitoring is likely to be high risk, and many organisations will want to consult staff or their representatives.
Scope-limited access helps here: you decide which users Nexi covers and who can see the results. We help you plan the rollout so the reporting is useful without being intrusive, and we suggest keeping productivity insight at team level unless there is a specific reason to go further.
How Nexi AI is licensed
Nexi AI is licensed per user, as a separate licence alongside DefensX browser security. Because Nexi works from the telemetry that the DefensX secure browser collects, the users it covers need to be running DefensX browser security as well; we confirm the right combination when we quote. You do not have to cover everyone with Nexi: you can license it for the teams you want insight into and keep the browser security edition across the whole workforce.
Prices depend on the number of users, the browser security edition and the term, so ask us for a quote. Licences can be added or removed as your needs change.
How we help
We check that your DefensX deployment collects what Nexi needs, agree the scope and access rights with you, and help with the staff communication and impact assessment side. Once it is running we can review the first reports with your leadership team and adjust the scope. Licences sit on your Forever Systems invoice with the rest of your subscriptions. Contact us to discuss a pilot.

Contact usFrequently asked questions
Do I need DefensX browser security to use Nexi AI?
Yes. Nexi AI runs on the DefensX secure browser and works from the telemetry it collects, so the users Nexi covers also need DefensX browser security. We quote both together.
Does Nexi AI use our data to train AI models?
DefensX states that customer data is used for inference only and is never used to train external language models, and that prompts and responses are encrypted at rest inside its secured browser container.
Is using Nexi AI legal under UK GDPR?
It can be, but it is a form of monitoring workers. You need a clear purpose, transparency with staff and a proportionate scope, and the ICO expects a data protection impact assessment where monitoring is likely to be high risk. We help you plan this before rollout.
How do people ask Nexi AI questions?
Through real-time chat, dashboards, weekly PDF reports and scheduled digests, and through a chat interface in messaging apps such as WhatsApp and iMessage.
