Volunteers compile the list of links by hand, thus creating a high-quality index of deep web content across dozens of categories. There is no official data available, but most experts agree that the invisible web is several times larger than the visible web. The true size of the internet is unknown, and the same goes for the invisible web. However, the invisible web can be roughly divided into the deep web and the dark web.
Exploring the dark web requires specialized knowledge and tools due to its anonymous nature and the use of encryption to maintain user privacy. It’s important to note that while the dark web can be used for legitimate purposes, such as protecting the privacy of activists and journalists, it can also host illegal activities. Therefore, caution and awareness of legal implications are paramount when accessing it. Dark web search engines are specialized tools that allow users to perform web searches within the dark and deep web. Unlike traditional search engines like Google or Bing, these tools operate on the Tor network — a hidden ecosystem where most content is intentionally obscured from public view. Instead of browsing indexed links, dark web engines scour encrypted, often anonymous websites (“.onion” sites) that do not exist on the clear or surface web.

- In 2025, I used Haystak to find a historical .onion archive of a defunct hacking forum for a cybersecurity report.
- To get the full potential of SearXNG, especially for deep web content, use the Tor browser.
- From the main search page, you can link through to sites of specific institutions and even tribal governments, accessing all kinds of records from birth and death certificates to old legal information.
- Determine the risk of a cyberattack based on your level of dark web exposure.
Supercharge Your Security With Our Dark Web Monitoring Tool
According to my personal experience, Deep Search seems to provide pretty accurate and useful results, unlike others who spam users with spam links. Another noteworthy feature of Deep Search is that it provides a list of marketplaces, exchanges, and websites involved in scamming users. Onion Search is a search engine for the dark web that enables users to find and access Onion sites.

Online Best Dark Web Search Engines For Tor Browser

Although it’s not a search engine, it offers a categorized directory with indexed links to .onion web pages. While the Hidden Wiki isn’t entirely unrestricted, and uses filters to block many dangerous sites, it still lists some dubious sites that other search engines block. Keep reading to learn about the top dark web search engines and how to use them to more safely navigate the dark web.
What Is SecureDrop?
The Tor browser is open-source and is used to access the dark web, where data is encrypted and routed through multiple relays before reaching its destination. The surface web—which we use for searching day-to-day information—is only its tip. Many more layers of hidden content can be found below—in the deep and dark web.

Windows Shortcuts That Will Cut Your Work Time In Half

Another important feature is the service’s attractive dashboard, which simplifies complex threat intelligence management tasks. Ignite integrates with existing security systems, enabling teams to manage threats efficiently without disrupting workflows.

Risks And Precautions When Using OSINT Tools On The Dark Web
Osint sources include newspapers, magazines, news, conferences, photographs, videos, social media accounts, blogs, press conferences, and academic documents. With the spread of the Internet and the increase in the use of social media, there has been a significant increase in OSINT sources. The point to be considered is collecting information from resources that do not require contact with the target. The combined and automated use of OSINT techniques allows a threat actor to reveal its name, location, IP address, or image. OSINT, or Open Source Intelligence, can scan to Decipher and find connections between criminals and other actors around them. Specialists can also use it to monitor information such as possible attacks and internal threats, as well as to neutralize or disrupt plans in real time.
The 12 Best Deep Search Engines To Explore The Invisible Web
It’s not just a shadowy corner of the internet filled with illegal activities; it’s a realm where privacy is prioritized and unique resources are abundant. For the curious explorer, a dark web search engine is an indispensable tool. But what exactly is the dark web, and why does it need special search engines? Let’s dive deeper and explore the nuances of the dark web, the tools for navigating it, and the essential role of a VPN like Forest VPN in this journey. It allows users to suggest new .onion sites, but it does not indicate how these submissions are vetted, if at all, which can lead to low-quality, potentially harmful links appearing in search results. However, its open model and user-driven content curation allow cybersecurity researchers and experienced professionals to access a wider range of dark web sites.
The Express plan is best for SMBs, while the other is for mid-sized and large organizations. Moreover, you can integrate this solution into primary tools like SIEM and SOAR, making it one of the best dark web monitoring solutions. To mitigate these risks while exploring the dark web, it is crucial to use a reputable dark web browser like Octo coupled with proxies for an added layer of security. Keep your software always up-to-date, exercise extreme caution when clicking on links or downloading files, and avoid sharing personal information. Understanding the inherent dangers of the dark web and taking proactive safety measures are essential for a secure dark web experience.
Similar to using a regular web browser to access the surface web, visiting the darknet is legal. Regardless of the browser’s anonymity, it is still illegal to commit fraud or engage in any illegal activity on the dark web. According to a 2020 estimate conducted by Prey Project (a security service platform), 57% of the dark web is illegal. The dark web isn’t indexed by regular search engines and is known as a hotbed of criminal activity. NotEvil is a valuable tool for navigating the dark web while maintaining privacy.
