Releasing my Windows 10/11 Hardening app, free, of course, else it wouldn't be here.
AtlantHarden is a free Windows 10/11 hardening application designed to improve system security by applying a comprehensive set of registry, policy, and configuration changes. It offers three profiles—Basic, Recommended, and Maximum—balancing security and usability, with the Recommended profile aiming to block real malware while preserving user experience. The tool includes hundreds of hardening settings, DISA STIG controls, ACSC Essential Eight compliance, attack surface reduction rules, and browser hardening across multiple browsers. It automatically backs up changes and supports silent deployment for enterprise use. The application is self-contained and requires administrator privileges. It is not a vulnerability or threat itself but a security hardening utility.
AI Analysis
Technical Summary
AtlantHarden v2.0 is a Windows 10/11 hardening tool that applies 579 security settings across registry, PowerShell, firewall, audit policies, and attack surface reduction rules. It integrates 354 DISA STIG controls for Windows 11, Edge, Chrome, Firefox, and Office 365 ProPlus, plus 34 ACSC Essential Eight settings. The tool provides three configurable profiles (Basic, Recommended, Maximum) to balance security and usability. It blocks common attack vectors such as Office macros, ransomware, credential theft, and living-off-the-land binaries via firewall rules. It also enhances PowerShell logging and browser security. Changes are fully reversible with automatic backups and system restore integration. The tool is free, self-contained, and supports silent deployment for enterprise environments. It modifies Windows security settings at the registry level and requires administrator privileges.
Potential Impact
This is not a vulnerability or exploit but a security hardening tool intended to reduce the attack surface of Windows 10/11 systems. By applying its settings, users can mitigate risks from malware, ransomware, credential theft, and other common attack techniques. The Recommended profile is designed to improve security without disrupting usability or performance. The Maximum profile enforces stricter controls suitable for high-security environments but may impact user experience. There are no known exploits or threats associated with this tool itself.
Mitigation Recommendations
This is a security enhancement tool, not a vulnerability requiring mitigation. Users should ensure they create a System Restore Point before applying changes, especially when using the Maximum profile, due to significant system behavior modifications. The tool automatically backs up all changes and supports full reversal. Administrator privileges are required for deployment. For enterprise use, silent deployment and configuration import/export are supported. No patch or fix is applicable.

Reddit Discussion
I used to have a hardening script for years, but now AI made it easy to convert my hardening script into an app.
It's beyond just a few settings - all of the ones in the recommended profile are battle-tested (I used to work in Microsoft's security consulting division in the Middle East).
Feedback is welcome, I promise to take into account and fix all issues reported here.
Here's the official description:
Most hardening tools overcorrect. Blindly applying a full DISA STIG to a personal or power-user machine wrecks it: it disables your password manager, kills InPrivate, turns on Controlled Folder Access that blocks your own apps, and demands a BitLocker PIN on every boot, all for compliance checkboxes that add little real security.
AtlantHarden v2.0 is built around a smarter idea: stop how malware and attackers actually get in and run, and skip the friction that does not stop them. Comprehensive when you want it with the Maximum profile, sensible by default with Recommended. Every change is backed up automatically and fully reversible.
Features
- 579 hardening settings across registry, PowerShell, firewall, file associations, audit policy, and ASR rules
- 354 DISA STIG controls across Windows 11 (V2R7), Edge (V2R5), Chrome (V2R11), Firefox (V6R7), and Office 365 ProPlus (V3R5)
- 34 ACSC Essential Eight settings (July 2024) with live compliance scoring
- 3 one-click profiles: Basic (95 settings), Recommended (318), and Maximum (579), each fully reviewable before apply
- Recommended profile is gaming and performance safe and leaves your password manager, InPrivate, and history working
- 19 Attack Surface Reduction rules blocking Office macros, ransomware, credential theft, and script droppers
- LOLBin firewall rules blocking certutil, mshta, wscript, regsvr32, and wmic from the network
- File association neutralization opening dangerous script types (.js, .vbs, .hta, .scr) as text
- Browser hardening across Edge, Chrome, and Firefox simultaneously
- PowerShell logging triad: script block + module + transcription
- Registers itself as allowed for ASR and Controlled Folder Access so it never locks you out
- Full backup with automatic pre-change snapshot, .reg export, and System Restore integration
- Silent deployment via CLI for enterprise fleets, plus configuration import and export
- One-click HTML security report with STIG and ACSC compliance metrics
If the mods allow it, I'll add a download link in here - else, just google "Atlant Harden"

P.S. As this is free, I hope I am not breaking the no spam and no advertising rules
