That's somewhat telling and can be used to "track" you, consider reading on non-Reddit privsec learning resources like Privacy Guides itself which you already know, PrivSec.Dev, madaidan's Insecurities and the like.

Considering the offer is legitimate (something I won't comment on), you shouldn't do most of these things, in my opinion. Don't mess with what'll be other people's phones. Sell them Pixels pre-installed with GrapheneOS and print papers with Auditor attestation instructions and maybe a few QR codes directing them to relevant documentation and privsec learning resources, such as the GrapheneOS documentation first and foremost, Privacy Guides, madaidan's Insecurities, PrivSec.dev, Seirdy's Home, Wonderfall's Lab, etc...

i never used it myself. only learned about it from security experts like madaidan or hardening guides like this one.

Tripwire's open source distribution specifically. It supports SHA1, MD5, HAVAL and CRC32. All individually are not cryptographically secure but the combination of them makes it unlikely that an attacker could modify a single file in such a way as to find a collision on multiple hashes.

I'm looking at current options, this[1] for example is packaged for Fedora, which is my daily driver.

But then I got to thinking, if I'm going to do a clean Fedora install for the tripwire (it's best practice) I might as well try Fedora Silverblue[2]. Silverblue is an immutable system so it kinda makes a tripwire less useful because no one can change any system files. Only files in your home directory and /etc can be modified statefully.

Active Measures - Includes (IDS/IPS) such as open-source Suricata or Snort on pfSense, and File Integrity Monitoring (FIM), such as the commercial Tripwire and dated, open-source Tripwire, or the open-source Wazuh installed on servers. These can be combined into a Security Information and Event Management (SIEM) system like the open-source solution, Security Onion. Wazuh itself has evolved into a SIEM.

This reminds me of the general idea behind [Tripwire](https://github.com/Tripwire/tripwire-open-source) for macOS. I last looked into it back in 2005 (we went with other approaches), so it may have changed since then, but it monitors for changes, and allow you to revert them or deploy them to other computer (as in a lab, etc).

Yes, tripwire. https://github.com/Tripwire/tripwire-open-source
