![]() Slack has several other mechanisms in place that are meant to protect an organization from breaches and intruders. However, Slack has a feature called Enterprise Key Management, which adds another layer of protection, and allows administrators and business owners to have more control of the data that is being shared within their organization. Slack does use encryption, but it is not end-to-end encrypted. Slack is popular for good reasons: it's easy to use, pretty much never crashes, has a bunch of cool features, and is affordable. Unless you're really interested in cybersecurity and online privacy, you probably haven't even heard of Wickr and Wire, but you've almost definitely heard of Slack, if not used it to communicate with your colleagues already. Plus, it has been independently audited, and remains compliant with frameworks such as the General Data Protection Regulation (GDPR). Unlike Wickr, Wire is open source and its code is available on GitHub. Meanwhile, calls are encrypted with Datagram Transport Layer Security (DTLS) and the Secure Real-time Transport Protocol (SRTP). Wire uses the Proteus encryption protocol, which is based on the Signal Protocol, to encrypt messages. The Basic version can handle up to five users, which is obviously not enough for most businesses, so medium-sized and large teams can opt for either Enterprise or Government-the latter actually is used by governments, which speaks volumes about the app's security. ![]() The app added end-to-end encryption two years later, and reoriented itself towards businesses in 2018, when it released a collaboration solution.Ĭustomers can choose between Wire Basic (free), Wire for Enterprise (from $7.65), and Wire for Government (you need to contact sales to get a quote). Wire was created by a group of former Skype employees and launched in 2014. Additionally, Wickr regularly sends out transparency reports and allows third-party audits, and its crypto code is publicly available. ![]() Private keys are stored on user devices, and only public keys are transmitted through company servers.Īll messages sent through Wickr self-destruct after a while (you can adjust the expiration time), and cannot be accessed or recovered in any way once destroyed. It is 256-bit end-to-end encrypted, and uses a new key each time a message, file, or call is encrypted. In fact, Wickr is one of the most secure messaging apps available. On the security and privacy front, Wickr absolutely delivers. Silver, Gold, and Platinum respectively cost $4.99, $9.99, and $25.00 monthly per user, and are packed with a lot more features. Basic is free, and good for small teams of up to 30 users. ![]() The latter two are better suited for businesses and large organizations.īut regardless of which version you choose, you will have to pick between Basic, Silver, Gold, and Platinum options. There are three versions of it: Wickr Me, Wickr Pro, and Wickr Enterprise. Wickr hit the market in 2012, and though it was initially developed as a mobile chat app, it is now available on Windows, Mac, and Linux as well. ![]()
