A default-installed Windows 11 endpoint in 2026 has eight major attack surfaces enabled out of the box that should not be: NTLM authentication, LM/NTLMv1 fallback in many cases, unsigned-driver execution, LSASS access from non-protected processes, BitLocker without PIN, Office macros from internet sources, SmartScreen passable via mark-of-the-web bypass, and PowerShell without script-block logging. This Windows 11 enterprise hardening guide for 2026 is the consolidated 10-phase rollout that closes every one of those gaps — aligned with the CIS Microsoft Windows 11 Enterprise Benchmark, Microsoft’s Security Baselines, and the operational realities of running a multi-thousand-endpoint fleet under Intune, Group Policy, or both. ...

NTLM has been on borrowed time for two decades, and Microsoft made it official: as of late 2023 Microsoft formally announced that NTLM is deprecated, with Kerberos and the new Negotiate-based authentication taking over. Windows 11 24H2 and Windows Server 2025 ship with NTLMv1 fully removed, and Microsoft strongly recommends auditing and disabling NTLMv2 wherever Kerberos can take over. This guide walks through how to disable NTLM in Windows safely — auditing first, staging the rollout, and rolling back cleanly if something breaks. ...

OSINT — open-source intelligence — is the systematic collection of public data to answer a specific question. Done well, it’s the single highest-leverage skill in incident response, threat intel, due diligence, and bug bounty recon. Done poorly, it’s hours of dead Google links. ...

Most SIEMs fail not because the technology can’t keep up but because the detection content is bad. This guide walks through how a detection engineer actually thinks about a rule, from data onboarding to deployment. The Lifecycle Threat → Hypothesis → Data → Query → Tuning → Deploy → Measure → Retire Skip any step and you produce noise. ...

The Windows privilege escalation surface has narrowed since the days of unquoted-service-path goldmines, but it hasn’t disappeared. Token abuse, misconfigured services, and overlooked AutoLogon registry entries still net SYSTEM on a meaningful percentage of corporate hosts. Step 0: Baseline whoami /all systeminfo | findstr /B /C:"OS Name" /C:"OS Version" /C:"System Type" hostname whoami /all is the single most informative command. Look at: ...
