Welcome back to IT Pro Tuesday!

We're looking for your favorite tips and tools we can share with the community... those that help you do your job better and more easily. Please reply or leave a comment with your suggestions, and we'll be featuring them in the coming weeks.

As always, we’re updating the full list on our website here. Enjoy.

But on with this week's tools...! Here are the most-interesting items that have come across our desks, laptops and phones this week. Hornetsecurity has no known affiliation with any of these unless we explicitly state otherwise.

A Free Tool

Certificate Transparency Project is Google's answer to the vulnerabilities to compromise and manipulation of certificates and issuing CAs. It provides an open framework for monitoring and auditing HTTPS certificates, so you can search all the certificates in active Certificate Transparency public logs for a given domain. Site owners can use the tool to check their domain names and see if there have been any problematic issuances of certificates referencing their domains. hard_cidr tells us, "This site from Google is pretty handy to view the cert history."

A Cheatsheet

"Is it worth the time?" looks like a cartoon, but it is actually a useful, at-a-glance cheatsheet to help you determine how long you can work on making a routine task more efficient before you spend more time than you save. Kindly shared by kingtudd, who explains, "I do escalation tasks and automation at my company, and I use this thing all the damn time."

Another Free Tool

MAC Address Vendor Lookup enables you to retrieve OUI vendor information, detect virtual machines and possible applications and read the information encoded in any MAC. Also returns results of the site's own research regarding that MAC address or the OUI. Kindly suggested by SDN_stilldoesnothing.

One More Free Tool

Fess is an OS-independent, scalable search server with an easy to configure, browser-based admin GUI that puts the power of Elasticsearch at the disposal of those with no prior experience using the tool. Contains a crawler that searches many types of documents on the web, file system or database and provides search/click log and statistics. Ceyax suggests it for indexing because "it's free and uses ElasticSearch, it has an OCR Option and you can get it running quickly with Docker."

P.S. Bonus Free Tools

PrimoPDF is a Windows app for creating PDF documents and editing their settings. Offers templates to create documents optimized for ‘Screen,’ ‘eBook,’ ‘Print’ and ‘Prepress’ use as well as ‘Custom.’ Our thanks for the recommendation go to yazzanz.

IP Subnet Aggregator is a web tool that uses your list of CIDR networks to calculate all the narrowest-possible CIDRs for the entire set. Simply enter your list of IPv4 or IPv6 CIDRs and it instantly calculates the whole range for you. Our thanks for this one go to the author, error404.
