Key Windows 11 Security Enhancements for Addressing Today’s Aggressive Threat Environment

Keeping your systems and business applications up to date with patches and fixes is crucial for maintaining operational security. So if you haven’t yet started planning your Windows 11 transition, now is the time to do so to protect your data and operations from potential threats. Otherwise, your organization could face significant security vulnerabilities, increased downtime, and compatibility issues after Microsoft ends support for Windows 10 on October 14, 2025. 

As data breaches become costlier, with the proportion of businesses experiencing breaches over US$1 million rising from 27% to 36% this year, staying ahead of these problems will help you defend your organization against the growing complexity of modern cyber threats. 

Upgrading to Windows 11 sooner will also help you take advantage of the new advanced features available to strengthen your cybersecurity posture. A significant upgrade over Windows 10’s security measures, these enhancements offer users a more secure, resilient computing environment. Below, we explore the key Windows 11 security features you need to know and their importance in protecting against today’s digital dangers. 

Five Windows 11 Security Features You Need to Know 

While there are many new Windows 11 features and benefits worth nothing for their impact on your organization’s productivity, the updated security options are particularly important for protecting organizations against vulnerabilities that could compromise your data integrity. 

1) Experience enhanced hardware security with TPM 2.0 

One of the standout new features is that Windows 11 requires Trusted Platform Module (TPM) 2.0 in all compatible devices. Most modern PCs now come with TPM 2.0 embedded in the hardware, creating a strong foundation for maintaining system integrity.

This dedicated security chip works to create a secure environment at the hardware level, storing cryptographic keys, credentials, and sensitive data in a tamper-resistant unit. Unlike software-based security, TPM operates independently of a device’s main CPU and memory, which is harder for hackers to exploit. As a result, organizations can strengthen their protection against sophisticated malware, unauthorized access, and physical sabotage. 

Several Windows 11 features rely on TPM 2.0 to function properly, including: 

  • Secure Boot: Secure Boot prevents unauthorized software from loading during startup, protecting against rootkits—a malware that gives hackers remote access to a device. 
  • BitLocker Encryption: BitLocker encrypts entire drives, ensuring that only authorized users can access your organization’s data. 
  • Credential Guard: When you enable Credential Guard, you can isolate and protect user credentials, reducing the risk of credential theft. 

2) Create layered protection with Virtualization-Based Security (VBS) and Hypervisor-Protected Code Integrity (HVCI) 

Windows 11 also fortifies your defense against advanced threats by leveraging two mechanisms: 

  • Virtualization-Based Security (VBS) leverages hardware virtualization and the Windows hypervisor to create a secure, isolated space for your computer memory that prevents malware attacks from affecting your critical system processes. 
  •  Hypervisor-Protected Code Integrity (HVCI), a VBS feature that works within that secure space, checking the trustworthiness of all system files and drivers before they are used. This protects your system from being compromised, even vulnerabilities exist that malware could exploit. 

Windows 11 uses these mechanisms to create a layered cybersecurity approach, which is key for experiencing holistic protection and minimizing a breach’s impact even if cybercriminals managed to penetrate one of your defenses. 

3) Improve access control with Windows Hello for Business enhancements 

Windows Hello for Business is Microsoft’s biometric authentication platform, offering a faster and more secure way for users to access devices and applications. It is designed to provide organizations with a passwordless access control method, moving away from traditional passwords—one of the weakest links in digital security due to their vulnerability to credential theft, phishing, and brute-force attacks. Instead, users can log in using facial recognition, fingerprint scans, or PINs.

In Windows 11, Microsoft significantly improved the security, convenience, and overall user experience of the tool. They introduced enhanced algorithms and anti-spoofing measures that more effectively detect fake biometric inputs, such as photos or masks. Windows Hello in Windows 11 also benefits from enhanced integration with Azure Active Directory (AAD), streamlining access control across both cloud and on-premises environments, making it easier to manage authentication at scale.

4) Enhance your continuous monitoring with Microsoft Defender 

In Windows 11, the company significantly upgraded their built-in security suite, Microsoft Defender, to provide stronger endpoint protection, particularly when it comes to continuous monitoring, an important cybersecurity measure for maintaining an up-to-date view of your security posture and swiftly reacting to any suspicious activity. 

They introduced several key features for overseeing your Windows 11 devices, including: 

  • Automated Threat Remediation: You can reduce your organization’s response times to security incidents by automatically detecting and neutralizing threats without employee intervention.
  • AI-Driven Threat Detection: This feature allows you to detect new types of malware before they cause harm by spotting unusual behaviors or patterns that suggest a threat, even if there’s no known signature.
  • Advanced Threat Analytics: Access detailed insights into attack vectors to better understand the security incidents you encounter and respond effectively to prevent future threats.

5) Explore a new category of device with Secured-Core PCs  

As part of the rollout of new Windows 11 devices, Microsoft introduced Secured-Core PCs. These computers combine hardware, firmware, and software security features in a brand-new package to comprehensively protect organizations against cyberattacks. They deeply integrate the operating system into the hardware, protecting even the most sensitive parts of the device by default.  

These devices leverage features that we discussed above, such as VBS, HVCI, and TPM 2.0 to safeguard your organization’s data against vulnerabilities and advanced cyberattacks. Their firmware protection stops malicious code from accessing low-level components that are traditionally hard to secure. Meanwhile, the device’s advanced memory protection guards against the common exploit tactic of manipulating memory. 

This heightened security is especially helpful for organizations that deal with strict compliance requirements and security standards, such as healthcare, finance, and government institutions.
