Postini Alternatives

Did you let your Postini installation slip away when Google shut the service down? Bi101 can help you find a solution for securing your email from malware and fits your future.

At its height, Postini was the world’s largest email collaboration, spam, malware, and email archive solution. In 2005, its 10 data centers were processing 2.5 billion emails weekly, and it was the go-to solution for some of the biggest customers and millions of individuals.

When the service was purchased by Google in 2007, its services became tightly integrated with Gmail, and in 2012, Postini was shut down completely. Google said the services were being rolled into Google Apps (now G Suite), but the discontinuation still left many without an email spam and archiving solution that worked for their business. They had to look elsewhere for new products that could deliver the same way Postini did.

Back during that transition, Bi101 helped transition hundreds of partners toward other viable solutions. That transition period is long past, but we still offer a number of Postini alternatives that are even more feature-rich and ready to handle the complexity of today’s computing. Get in touch and we’ll find the option that works best for you.
