Introduction
After conclusion of a troubleshooting mission, it is COMCERT's policy to completely remove all data from the tool's HDD and SDD by reimaging the server.
We also offer optional data erasure with certified data erasure software.
Please note that wiping a server can take from a couple of hours to more than a week and may include an extension of the rental period.
Solution
 | Wiping a server in accordance to these standards can take from a couple of hours to more than a week. |
