AI security audits for e-commerce and web platforms
Made by Agent RidgeWebsiteOn XFrom its maker: Test the security of your e-commerce sites and web platforms. €500 AI security audit, visual evidence and PDF reports.
Hide your identity from Ai in documents.
From its maker: Cover helps you stop leaking your identity every time you send a document to Ai for help. Drop your PDFs into Cover first.
Cover sensitive info on your Mac while you screen share
From its maker: Scrim is a macOS screen privacy utility that creates persistent, floating overlay masks to hide sensitive on-screen content during screen sharing, presentations, livestreams, and demos. Built natively in Swift for macOS Sequoia, it runs entirely offline with zero telemetry.
Netfox turns raw network data into plain English on your Mac
From its maker: Netfox turns raw network data into plain English on your Mac: decode every device, see what it exposes, and catch services left open. No cloud, no account.
Mac network monitor with optional threat blocking
Made by Philip SeifiWebsiteOn XKilobat watches your Mac's network connections and tells you which app, process or recognized coding agent is behind each one. It can block destinations on public malware, phishing and scam lists, and it can block trackers too.
Tracker blocking is free. Threat blocking and the agent guard need Pro, which is $29 once, with a 7-day trial. Its maker, Philip Seifi, is plain about the limits: it does not scan files, and a threat that is on no list can still get through.
The desktop app is proprietary, and a separate command line tool is open source under GPL-3.0. It runs on Apple silicon and Intel and needs macOS 14 Sonoma or later.
Look for who makes it, exactly what it monitors or blocks, and whether it is signed and notarized.
There is no single best one for everyone. MacPip lists 5: Agent Ridge, Cover, Scrim, Netfox, Kilobat. If you want it free, look at Scrim. If you would rather pay once than subscribe, look at Kilobat. If you want it to run natively on Apple silicon, look at Cover. If you need it to work offline, as its maker says it does, look at Cover.
Yes. With a free version on MacPip: Scrim, Netfox, Kilobat.
With a one-time option, so you can avoid a subscription: Scrim, Kilobat.
By their makers' word or by our check: Cover, Scrim, Netfox, Kilobat.
Each has a dated report on its page: Agent Ridge.
Apps a person has checked come first, newest check first, then the rest by when they were added. Payment never changes the order, and sponsored rows are labeled and kept apart.
