One of the major struggles in bug bounty hunting is to collect and analyze data during reconnaissance, especially when there are a lot of tools around but very few that offer actually useful results. The job of eliminating false positives and unrelated data from your recon becomes harder as the size of your target increases. Most popular tools used by bug bounty hunters like Knockpy, Sublist3r, and Subfinder are command line based and often difficult to use when the size of the target becomes bigger. With a lot of results, it becomes harder to filter out the most important ones, and this causes confusion. However, with an advanced backend and an amazing UI, this process can be made much simpler. Spyse is that revolutionary advanced reconnaissance automation framework which every bug bounty hunter needs.

At the core of reconnaissance is OSINT and data analysis, one needs to analyze a target and map out its infrastructure efficiently. To become familiar with your target's attack surface, you need to perform recon on your targets in a proper manner and gather information about its assets. For that, it's crucial to enumerate all the assets belonging to the target – every sub-domain, IP address and related domains, and by doing so, one can easily spot the low hanging fruits like sub-domain takeovers that can have a huge impact. Spyse simplifies this process and makes your life easier by doing the most difficult job of asset enumeration for you which includes every IP address, sub-domain and domain related to your target. Not only that, it also offers an advanced, yet easy to use, and clean user interface to filter results as per your requirements, with a lot more asset-related and useful OSINT data of your targets than you will ever need.

Faster Reconnaissance

Be the fastest in reaching your target's assets. Bug Bounty Hunting is a rat race – the faster you are able to fully analyze your target's attack surface, the more the chances of scoring a bounty. There is competition in every field, but with close to a million bug bounty hunters working across platforms – at any given time there may be hundreds of thousands of bug bounty hunters working on a specific target of a bug bounty program, which leads us to the biggest hurdle – time. If you are not able to optimize your reconnaissance workflow and reduce the time you spend on your targets, you will lag behind the others who will find bugs faster than you. If you are at par with the others, and stick to the usual tools, you still stay average – but with an industry-leading solution like Spyse, you not just become fast but faster than the others.

With Spyse, its just a plug-and-play operation

Spyse makes Recon an effortless plug-and-play operation. It has all the necessary data about your targets already collected, even before you begin to hunt on a target, and the advanced search filter mechanism is way better than most command-line based open source tools. This saves you a lot of time in your recon phase – the time which you can later spend in further analyzing the target in depth and reaching bugs faster than the others.

If you are slower to reach a target, there might be a possibility that someone else already found a bug in that target and you are left with a duplicate. Because Spyse cares about your time, they have already gathered a large amount of data, and they keep updating their databases at any given time, ensuring the data is up-to-date and relevant. With the Spyse platform, you can save a lot of time and effort to find vulnerabilities in targets before the other hunters, saving you from duplicates.

Doing Recon on New Targets has never been easier

If you run the traditional tools just after you get access to a new target, it might take days to just collect the data on larger targets and, yet more time to analyze and make sense of it. With Spyse's advanced solution – advanced search feature can get you to the same results in less than a fraction of a second.

You can search for information about your target domain name (say,, from Spyse's collection of over 4.5B domain name records, all indexed with accurate and advanced data, which will help you in performing recon more easily.

Not just another Cybersecurity Search Engine

Spyse is not just another cybersecurity search engine, it's an advanced yet simple Reconnaissance framework of sorts. Unlike Censys and Shodan, Spyse offers a user friendly filter which doesn't make use of advanced query syntax.  The simplicity of their advanced search feature is just amazing, and since reaching your target's assets and filtering data should never be a difficult task, it makes Spyse a better tool for recon at ease. With Spyse, you don't have to spend time getting used to Advanced query syntax unlike most other OSINT tools. Spyse's advanced search feature is aimed to be simple to use, user friendly yet efficient and precise. The advanced search lets you precisely hit your goal by tuning the search parameters to exactly the targets you are after – minimizing false positives and inaccurate results.

Advanced Search Filter to find Apache servers belonging to a target

For example, if you are looking for Apache servers in a particular target's infrastructure, you can set the search filters to match your target's Organization name (domain name or, AS or, IP ranges) and add another filter, Site info > HTTP Header > Name and Value to Server and Apache respectively, and let the backend handle the rest for you. The search filters are implemented using intuitive UI and natural language without the need of advanced search query language unlike most other cybersecurity search engines.

Managing Recon Data

Spyse has taken care of it. It is difficult to manage vast amounts of reconnaissance data. Some hunters who have advanced development knowledge prefer to make their own automation with a proper backend and database of targets, yet they tend to miss on lots of data and find it hard to manage all this data, and correlate it. However, with Spyse you don't need advanced development skills, because Spyse, as an advanced cybersecurity search engine, crawls, collects and correlates advanced in-depth data about your targets. Developing a web application and backend to manage the recon data is a lot of work for any hunter, but with a powerful reconnaissance solution like Spyse, you can reduce your efforts by as much as 90% and save the time you would have otherwise spent running manual command line tools to manage your recon data.

Spyse has collected and indexed over 4.5B domains
Spyse has gathered data of over 217.1M hosts with open ports, indexed 4.5B domains, 66M SSL/TLS certificates, 371M email-related data, 143.7K vulnerabilities, 1.2M organizations and more. Learn more about their data statistics here.

Export Recon Data in JSON/CSV Format

Spyse has a very handy data export feature that lets you quickly export your scan data in JSON and CSV format. Whether you like to see your data in Excel or, implement it in your own application or, visualize it using ElasticSearch, Spyse has got you covered. It also makes it easier for you to use the exported data with other custom tools (most tools support JSON/CSV data, as its a common format).

Not just that, Spyse has integrated certain features like advanced filters that help manage your recon data even more seamlessly.

Large Scope?

No problem! Spyse can easily handle a lot of information. With conventional tools you can miss a lot of information while working on bug bounty programs with large scopes but with Spyse – it's no longer a problem!

Spyse has gathered an incredibly large dataset of assets, and it's next to impossible to miss any important asset belonging to your targets with the Spyse search engine.

Yahoo has almost 143.4k sub-domains and hundreds of thousands of IP addresses. Click here to explore the potential of the powerful advanced search engine filtering system to enumerate all of Yahoo's sub-domains.

Working with large scope targets is now much easier with Spyse's advanced search filters

Having to deal with so much data on large scope bug bounty targets during recon makes it incredibly difficult and tedious to scan these assets, and perform reconnaissance at scale. However, Spyse collects and updates this data on a regular basis, and indexes it, making it easier to filter out small bits of information that is important for your recon.

Filtering sub-domains by Response Code

You can also filter your target's assets by response code (for example – 200 status code, for valid request), which helps you quickly find interesting assets from a large number of target sub-domains and domains. This is a very handy feature while doing recon on any target, as it gives you a quick overview of the publicly accessible assets of your target.

Data Visualization

The web interface lets you visualize your target's data more efficiently and in a better manner than other tools. This helps you take decisions easily, and find vulnerable assets more easily than using conventional tools. With bigger targets like Yahoo having as many as 143.4k sub-domains, using conventional tools like subfinder becomes harder, but with Spyse you can visualize the relationships between different assets, and decide where to spend your time while hunting on the target's assets.

Spyse's advanced data gathering solution gives you an extremely intuitive interface to search through loads of data and offers you a visual approach to dealing with large amount of recon information.
