1. Mandatory TPM 2.0 and Secure Boot for PC
   To play Black Ops 7 (in the beta and at launch) on PC, your system must have TPM 2.0 enabled and Secure Boot turned on. These requirements are enforced from startup, not optional. 

2. Remote Attestation
   Beyond just having those features enabled locally, the game will use a remote verification system (“remote attestation”) to confirm that the TPM and Secure Boot settings are valid. The verification will happen through cloud servers (Microsoft’s Azure). This is meant to prevent cheating via spoofing or bypassing those protections. 

3. Upgraded Machine Learning & Detection Systems
   The anti-cheat team (Ricochet) has been gathering data from millions of hours of gameplay (from BO6 and elsewhere) to improve how suspicious behavior is detected. The improvements aim for faster, more accurate detection of cheats or external hardware tampering. 

4. Phased Roll-Out / Warnings Before Enforcement
   These features first showed up during Black Ops 6 Season 5, but players were only warned if their systems didn’t comply, not blocked. With BO7, however, enforcement is mandatory: if the required security features aren’t enabled, the game will refuse to run. 

5. Effectiveness Claims
   According to Activision, the updated system is showing strong results. They claim ~ 97% of cheaters caught are banned within 30 minutes of their first sign-in with cheats. Also, under 1% of cheating accounts supposedly make it into matches with their cheats still active. 

What It Means for Players

• Hardware & BIOS Readiness Is Important
  You may need to update your motherboard’s BIOS, switch from Legacy boot to UEFI, ensure the disk partition style is GPT (instead of MBR), and confirm that the TPM module is version 2.0 (or use firmware TPM if available). If your PC is older, this could be a blocker. 

• Privacy & Performance
  Activision says the system only checks for TPM 2.0 and Secure Boot status and system integrity; it does not access personal files. Also, they assert these security checks happen at boot or startup, not continuously during gameplay, so there should be minimal performance overhead. 

• Potential Access Issues for Some Users
  Some players with older hardware or unsupported motherboard firmware have reported difficulties getting TPM2.0 or Secure Boot accepted even after enabling them. BIOS updates from manufacturers are rolled out more slowly in some cases. These issues may prevent them from being able to play BO7 unless resolved. 

• Stricter Enforcement Means Less Room for Error
  Because these requirements are enforced from the beta onward, you’ll want to make these changes ahead of launch to avoid any last-minute problems.
