CertDB Security of personal data. SSL stands for Secure Sockets Layer and, in short, it's the standard technology for keeping an internet connection secure and safeguarding any sensitive data that is being sent between two systems, like server and a client (for example, a shopping website and browser) or server to server (for example, an application with personal identifiable information or with payroll information). It does this by making sure that any data transferred between users and sites, or between two systems remain impossible to read. SSL uses encryption algorithms to scramble data in transit, preventing 3rd party from reading it as it is sent over the connection. This information could be anything sensitive or personal which can include credit card numbers and other financial information, names and addresses. TLS (Transport Layer Security) is just an updated, more secure, version of SSL. HTTPS (Hyper Text Transfer Protocol Secure) appears in the URL when a website is secured by an SSL certificate. The details of the certificate, including the issuing authority and the corporate name of the website owner, can be viewed by clicking on the lock symbol on the browser bar
Internet-wide search engine for digital certificates What information contains in Certificates? SSL/TLS Certificates link looks like a /C=US/ST=California/L=Mountain View/O=CompanyName LLC/CN=*.example.com C means Country, ST - State / Province, L - Locality, O - Organization, CN - Common Name. If CN has a sign “*.” it means, that Certificate was generated for domain and subdomains. Other information about certificate contains an algorithm of encryption, date of issue, date of expiry, fingerprint and serial number.

CertDB is the analysis tool designed by security researches for exploration of the certificate-driven data about websites, organizations and certificate issuers. Nowadays, every IT project requires data encryption - something that generates vast amounts of data for analysis and discovery of statistical and detailed information about specific companies, their business objectives and integration between them. Data, that has been generally used by IT security specialists alone, is now available for analysis by entrepreneurs, marketers and business analysts.
Scans every reachable web server on the InternetCertDB continuously scans every reachable web server on the Internet for digital certificates (SSL and TLS). And all of this information is available to query and analyze in real time. CertDB uses all publicly accessible entry points for analysis scanning to the most common ports of the entire IPv4 range. For example, analysis can be narrowed down to recently registered domains, soon to expire certificates, geographic location, company names and many more.
Digital certificates dataThe creation and expiry of digital certificates act as indicators of entrepreneurial activity in the IT space. The issuance of a new certificate marks the beginning of operations for some organization or an entrepreneur in a particular field or geographical region. The expiration of a certificate often indicates that the business activity is slowing down. See our examples of simple research on digital certificates data here.
Security expertsNeedless to say, historically, IT security experts expressed most interest in digital certificates based data. CertDB provides a convenient tool for security experts to perform relevant research and analysis.
