I don’t think many of you have heard of SPYSE (I didn’t before this interview) before, but let me tell you - they are amazing people, great developers and believe me when I say they are contributing great to information security community with their amazing tools and projects. I got interested and frankly heard about them when I checked out on certdb and findsubdomains projects - remarkable sites and highly recommended to have a look! I authored a review on their projects - CertDB is a free SSL Search Engine, and Finding Sub-Domains for Open Source Intelligence and have spoken highly of them. So, in last few days I got a chance to ask them some questions on their project CertDB, and their ongoing efforts to share with you all.

Many of us are in the security consulting business, or bug bounties, or even network intelligence and have now and then come across a need to find subdomains. The requirement can be from either side of the table - a consultant assessing a client’s internet presence, or a company validating its own digital footprint. In more than a decade, it has happened so many times that people are not aware of what old assets are they running, and hence can be exploited to either damage the brand image, or actual networks. These assets can also be used as the proxy or hops to gain access to thought-so-well guarded data.
