Your browser identified itself as a version of IE that was often shipped with default settings that were less than secure. Your internet experience could be made more secure by opening Internet Options in your browser, going to the Advanced tab and looking under the security settings for "Use TLS 1.1" and "Use TLS 1.2". Ensure these are turned on (checked). Doing so will enable your browser to support a higher quality of encryption on this and other websites. You will still be able to browse this site without turning on support for TLS 1.1 and 1.2, but we will have to use a lower level of encryption to accomodate you. See this question on Stack Exchange's Superuser forum from 2011 for more details keeping in mind the comments about TLS 1.2 non-support were made many years ago, and things have changed since then.

If the support for better cryptography has been turned on for your browser, thank you, and you can safely ignore this advisory.

The gold standard in data compression

Reduce file sizes by up to 95% and improve system performance

Year after year, the amount of data being stored and exchanged around the world increases at an exponential rate. Costs for data storage and transmission continue to grow, whether organizations maintain their files on premise or in the cloud. An efficient, flexible solution for data compression is essential for managing costs and resource demands.

Having introduced the ZIP file format nearly three decades ago, PKZIP continues to set the worldwide standard for data compression and file management.

Unmatched performance

With PKZIP, organizations can compress files by up to 95%, reducing storage costs and greatly improving file transmission times. PKZIP can handle even the largest compression tasks, with capabilities to include more than 2 billion files in a single archive and compress files over 9 exabytes in size. PKWARE’s lossless compression technology ensures that all data (including file metadata) is retained when a file is zipped.

Flexibility and administrative control

PKZIP is compatible with all major enterprise computing platforms and supports multiple archive formats, making it easy to exchange data across the organization efficiently and effectively. Users can compress files in several archive formats, including ZIP, TAR, BZ2, and many others.

Enterprise customers can use PKZIP’s policy manager to standardize compression activities according to organizational policies and best practices, helping maximize efficiency, system performance, and resource savings.
