How good is Windows Defender in 2025 – really?

In this special episode, we're doing a deep dive into the world of cybersecurity to take a close look at Microsoft's built-in antivirus solution, Windows Defender, in 2025. While many paid antivirus programs compete for users' attention, a central question remains: is Microsoft's free and automatically-enabled solution still good enough to effectively protect you from the increasingly sophisticated threats of the internet?

We'll analyze the strengths and weaknesses of Windows Defender in its current version. We'll explore its core features, such as real-time malware protection, the integrated firewall, and ransomware defenses. We'll also discuss to what extent the latest updates and AI-driven detection methods have improved its protection and whether Defender can truly keep up with the complex attack techniques often uncovered by security experts.

This episode provides a realistic overview of who Windows Defender is a sufficient solution for in 2025—whether you're a casual user or someone who uses their computer primarily for simple, everyday tasks. At the same time, we'll highlight the program's limitations, especially in comparison to comprehensive third-party security suites that often include additional features like a VPN, password manager, or specialized phishing protection.
