Screening disposable email signups? There are tools for that. 

But disposable email detection tools aren’t created equal. We ran an experiment comparing 14 of them, and we share the results here. Here’s a TL;DR version of the results in case you’re in a hurry.

We’ve released a new version of Website Categorization, with a major update to how websites are classified, how quickly results can be retrieved, and how categorization data can fit into advertising, brand-safety, web-filtering, and security workflows.

TL;DR

• Jake AI now has Bulk Analyzer to run WHOIS, DNS and IP lookups on whole lists.
• Two new tools extend it for security work: bulk website screenshot capture and domain brand impersonation detection.
• Jake AI has 25 WhoisXML API tools and runs independent lookups at the same time.

WhoisXML API analyzed 12.3+ million domains registered between 1 and 30 September 2026 that appeared in Newly Registered Domains to identify the most popular registrars, TLD extensions, and other global domain registration trends. This number rose by 5.9% from 11.6+ million NRDs last month.

We also determined the top TLD extensions used by 3.2+ million domains likely registered with malicious intent from the First Watch Malicious Domains Data Feed in September 2026. This number increased by 8.3% from the previous month.

Next, we studied the top TLD extensions of 1.07+ million confirmed malicious domains from the Threat Intelligence Data Feeds this month, which declined by 2.1% from 1.09+ million in August.

Finally, we summed up our findings and provided links to the threat reports produced using DNS and domain intelligence sources during the period.

TL;DR

• WhoisXML API’s VPN & Proxy Detection API is a new API with daily bulk data files that classifies IPv4 addresses as VPN, proxy, residential proxy, Tor, relay, hosting, or CDN traffic. 
• One of the things that sets the API apart is residential-proxy detection: we observe residential-proxy exits directly and attribute them to their network, while scan-based methods miss these exits because they have no proxy port to scan.
• The API is live now, with pricing starting as low as $1/month. Sign up to get an API key within minutes.

Whether you call it SSL or TLS (yes, everybody’s actually using Transport Layer Security nowadays, but SSL stuck around the way Kleenex did for tissues), the protocol that secures communications between a host and a server is critical for the modern web and yet it can fail in more ways than most people realize. 

In this post, we cover the different SSL security threats, their consequences, and how to reduce the risks.
