네트워크
본 문서는 시스템 수준에서 기기를 보호하는 다기능 광고 차단기인 Windows용 AdGuard에 대해 다룹니다. 이용하고자 한다면 AdGuard 앱을 다운로드해 보세요.
네트워크* 모듈은 네트워크 필터링 전용 모듈로, 여기에서 네트워크 관련 추가 옵션을 찾을 수 있습니다. 이 중 두 가지(트래픽 필터링 활성화 및 HTTPS 프로토콜 필터링)는 기본적으로 활성화되어 있습니다. 이는 웹 공간을 더 잘 필터링하기 위한 중요한 추가 예방 조치입니다. 대부분의 웹 사이트와 광고 네트워크는 현재 HTTPS를 사용하고 있습니다. youtube.com, facebook.com, x.com과 같은 많은 웹사이트에서 HTTPS 필터링 없이는 광고를 제거하는 것이 불가능합니다. 따라서 HTTPS 프로토콜 필터링 기능을 사용하도록 설정하는 것이 좋습니다.
이 모듈에서 AdGuard를 HTTP 프록시로 사용 확인란을 선택하면 AdGuard를 통과하는 모든 트래픽을 필터링하는 일반 HTTP 프록시로 사용할 수 있습니다. EV 인증서가 있는 웹사이트를 필터링 기능을 활성화할 수도 있습니다. EV(Extended Validation) SSL 인증서는 더 강력한 안전 보장을 제공하며, 해당 웹사이트 소유자는 EV 가이드라인에 정의된 철저하고 전 세계적으로 표준화된 신원 확인 프로세스를 통과해야 합니다. 그렇기 때문에 일부 사용자는 이러한 인증서가 있는 사이트를 신뢰하고 필터링하지 않기로 선택합니다.
마지막으로 프록시 설정 섹션이 있습니다. 여기에서 필터 업데이트, 새 버전 가져오기 등에 AdGuard가 사용할 프록시 서버를 지정할 수 있습니다.
SockFilter and other network drivers
In Network, you can also enable traffic filtering and choose which driver to use: SockFilter, WFP, or TDI.
WFP (Windows Filtering Platform) is a powerful driver, but it may present stability risks, such as occasional system crashes (BSOD) for some users.
The TDI driver is also available, but it is outdated and may cause filtering issues in some versions of Google Chrome. A temporary workaround exists, but it’s not a reliable long-term solution.
SockFilter is an experimental, lightweight kernel-mode network driver that works at the socket level (TCP/UDP). Instead of inspecting or modifying packets as they travel through the full Windows networking stack, a sock filter intercepts socket calls (e.g., connect, send, receive, bind) at a higher, more stable abstraction level. This makes it ideal for applications that need to monitor or control network activity without deep packet processing.
Currently, SockFilter Right is still unstable, and you may encounter bugs. When fully tested and implemented, SockFilter has the potential to bring several advantages over other drivers:
- It operates at a higher, socket-level layer: SockFilter works with socket operations rather than raw packets, making it less complex and more stable than WFP's low-level packet filtering.
- No interference with other network drivers: Because it sits above VPN, firewall, and antivirus WFP filters, it avoids filter-ordering problems and compatibility conflicts common in the WFP stack.
- Greatly reduced risk of NETIO-related BSODs: SockFilter doesn't run inside the NETIO packet pipeline, so it avoids the typical crash scenarios caused by WFP callouts mishandling buffers, classification results, or packet memory.
When it comes to disadvantages, SockFilter driver sees only socket-level operations and does not capture traffic generated by other kernel drivers or components that bypass the standard Winsock API. From a low-level networking perspective, this can be viewed as a limitation, since the driver cannot access raw packets or inspect non-socket traffic. However, for an ad-blocking application, this behavior is not just acceptable but optimal. All relevant traffic from browsers and user-mode applications goes through standard sockets, and that's exactly what we need to control. At the same time, ignoring low-level driver traffic removes unnecessary complexity, avoids compatibility issues, and keeps the system stable.
AdGuard VPN
The last section is dedicated to AdGuard VPN — an ideal tool that provides security and anonymity each time you browse the Internet. You can download it by clicking the Download button or go to the AdGuard VPN website by clicking the Homepage button.
How does AdGuard VPN work? Without going into technical details, we can say that VPN creates a secure encrypted tunnel between the user's computer or mobile device and a remote VPN server. In this way, data privacy is preserved, as well as the anonymity of the user, because a third-party observer sees the IP address of the VPN server and not the actual user's IP.
What AdGuard VPN does:
- hides your real whereabouts and helps you stay anonymous
- changes your IP address to protect your data from tracking
- encrypts your traffic to make it unreadable to third parties
- lets you configure where to use VPN and where not to (exclusions feature)
