The cognitiveSEO tool provides a unique analysis process that delivers Unparalleled Backlink Analysis, Content Audit and Rank Tracking for Every Site.

I have been using the site audit tool for a little while now and I have to say that it has some very nice features, including a very easy view of how your site architecture is being used (internal links).

Creating a secure app shouldn’t be that hard. Pangea makes it fast and easy with its Security Platform as a Service (SPaaS), which unifies the fragmented world of security into a simple set of APIs for developers to call directly into their apps.

At Fashmates, our main priority is speed to market. Pangea helped us focus on delivering user trust, using the Redaction API with security, scale and performance built in. Pangea was integrated by one developer in a few hours, enabling our dev team to focus on our core business. That developer was in a different timezone so by the time we were up in the morning it was done! There was no download or installation needed. They simply called the REST API for Redact. This meant they could implement it once and have multi-device support. We would recommend to anyone looking to improve their application’s security posture to try out Pangea’s developer friendly APIs!
