What’s your reason of concern - leaving Cisco docs behind or erasing disk? Either way it doesn’t matter. Cisco needs the laptop hardware so it can be recycled.
My reason of concern, not necessarily that of the OP, is that the asset team are just people, and people are prone to make mistakes, especially when they have hundreds or thousands of laptops coming in at one time to be re-imaged and turned in or given back out to Cisco contractors until the lease ends. If I re-image the laptop, then I know that my personal data is gone.
If you have personal stuff in your work laptop that you are worried about, it’s already too late.
I don't care if Cisco has my "personal" data because they won't bother to go view it in the backups. I care if they mistakenly skip re-imaging the laptop and it gets returned to the leasing company and then gets sold off with my data. Any of my personal data on the laptop is probably in HR systems somewhere, not just the backup system(s). I feel the same as @1lnj+1sP8MLcX.
To @1dqf+1sP8MLcX comment, while the expectation is to use it only for work, Cisco's policies are that we can use the system for "occasional" personal use. Some data, is jointly owned by Cisco and the Employee, i.e. Performance Reviews, ESPP purchases and sales, RSU grants, Paystubs, Benefits elections, etc. You DO have a right to ensure that those documents are removed.
Cisco would have a hard time prosecuting me to "the full extent of the law" if Code42 was misconfigured (that's on IT, unless they can prove I did something to disable it) because the expectation is that Cisco is backing up critical files, I'm doing my due diligence checking in my code into the source code management systems of Cisco's choice, storing documents in SharePoint, Box, or team shared network folders.
What if I want to declare it lost and to pay for it? I would for.at the drive but I am wondering if the bios could cobtain anything that could still call back to Cisco
Apple Macs, as long as the laptop is under lease, it's registered as a Cisco laptop and if you re-image it, it "checks" in and re-registers itself. Once it's bought out, that "registration" is removed and then you can re-image it as a non-Cisco device. I'm not sure how it works, but ran into that as I was re-imaging my old laptop I was turning in as part of the refresh process. It's super easy to boot off a USB bootable "recovery" disk, or macOS recovery partition, to then format the main OS & Data partitions and overwrite them w/ a clean install. Between the whole disk encryption, format, and installing an OS, you've scrambled the SSD enough that any un-overwritten blocks are not readable as data, it's just a block of random characters.
After 15+ yrs at Cisco, I've re-imaged every laptop I've turned in for refresh, re-imaged most laptops on my team before they returned them for refresh, and I've never had the Asset Team or HR contact them or me asking about why the laptop is "clean". In some cases, I was unable to re-install an OS, leaving the laptop non-bootable and it still wasn't an issue.
