Nobody smuggles office data out in a briefcase any more. They upload it to a personal drive in the same browser tab as their work, in thirty seconds, often without a dishonest thought in their head. This guide is about that tab.
Picture the most common data leak in a small office. It is not a hacker and it is not a spy. It is a well-meaning employee who wants to finish the quotation at home, so at 6:55 pm they open their personal cloud drive in the work browser and upload the customer file. The file is now outside every control the office has — no revoking it when they resign, no record it ever left. Browsers made this effortless, so browser policy is where the friction belongs. Browser Security Plus groups these controls under data leakage prevention: managing where browser data can go, what the browser remembers (passwords, autofill, cards), and which uploads and websites are acceptable. This guide applies those controls with honest expectations about what they can and cannot stop.
Browser data leaves by four everyday routes: uploads to personal cloud storage and file-sharing sites; paste into personal webmail, chat and free AI tools (a pasted customer list trains no one's model policy, but it has still left the building); sync, which copies the browser's saved passwords and history to personal devices; and the browser's own memory — autofill holding card numbers and addresses for whoever uses the PC next. Walk these four routes in your own office before opening the console. The policy you need is written by what you find, not by the full feature list.
Work from the memory outward. First, the credential cluster: password saving and card autofill off (after the password manager from the saved-passwords guide is in place). Second, sync: work browsers sign in with work accounts only, so nothing is exported to personal devices nightly. Third, the web side: use web filtering categories to block anonymous file-sharing and personal storage uploads from work browsers where your policy requires it — while deliberately leaving the office's own cloud drive working, because a block that stops the job creates the workaround. Pilot each setting; leakage policies fail socially before they fail technically.
Every blocked shortcut needs a visible front door. The employee finishing work at home needs managed remote access to the same file — the office cloud drive with their work login, from their home browser, under office control. The quotation that must go to a personal-looking address is usually a client's request — give staff a two-minute approval habit, not a banned one. Offices that only block, without providing, teach an expensive lesson: the leak moves to the personal phone, where there is no policy at all and never will be. Your goal is not a sealed building; it is that the easy path and the safe path are the same path.
Say this in the office note, plainly: a determined insider can photograph a screen with a phone, and no browser policy on earth stops that. Data leakage prevention is not an anti-spy wall. Its real job is the 95 percent case — the casual, convenient, unthinking leak, and the malware or rogue extension quietly uploading in the background, which the extension and download policies already narrow. Judged on that job, it works: it adds friction exactly where the accidents happen, creates a log where there was silence, and turns "we had no idea files were leaving" into "here is the record." Anyone selling you more than that is selling theatre.
Once a quarter, look at the aggregate picture — which categories were blocked, how often, from which groups — and share the summary with the team. Two things follow. False blocks surface (the "file sharing" category that turned out to be the tax portal), and get fixed in the open. And staff see the policy doing its stated job — stopping accidents — rather than feeling watched in secret, which is the moment leakage policies die. Data protection that the office understands is data protection that survives staff turnover, including yours.
Uploads, sync, autofill and the leakage reports — the full data leakage prevention section of the console is in the video.

It cannot stop a determined person with a phone camera, and no honest tool claims otherwise. The aim is to end accidental and convenient leaks, and to give the office a legitimate way to work from home so the temptation drops too.
Only if the office's own cloud is blocked by the same rule — so set the categories carefully, allow the office's approved storage, and pilot before the full rollout. Staff who need to send large files externally get a known, approved route; the policy targets personal accounts on work browsers, not file sharing itself.
No, and it does not pretend to be. Dedicated DLP watches files across the whole PC and network. Browser leakage prevention covers the browser — which is where most everyday leaks actually happen in a small office, for a fraction of the cost and effort. Offices with strict compliance duties may need both; most small offices need this layer first.
