About Element
Element is a secure, decentralized messaging and collaboration platform built on the open Matrix protocol, offering end-to-end encryption by default across all conversations. It enables organizations to maintain full digital sovereignty by self-hosting their own homeserver or using Element's managed cloud, without vendor lock-in. Trusted by governments, defense agencies, and enterprises across 25+ countries, Element bridges secure internal communications with cross-organizational federation.
Pros & Cons
Pros

- Open source and auditable — entire stack is open source, enabling independent security audits
- Cross-organizational federation — communicate securely with external partners on different servers
- No single point of failure — decentralized architecture means no central server outage takes down comms
- Used and trusted by governments and defense agencies in 25+ countries
- Bridges to Slack, Teams, IRC, and other platforms enable gradual migration
Cons
- Steep learning curve — self-hosting Synapse requires significant technical expertise
- UI feels less polished than Slack or Teams, and threading can be clunky
- Mobile push notification reliability issues reported on some Android devices
- Community tier has no official support; paid tiers require contacting sales
- Two confusing mobile app versions (Element and Element X) exist simultaneously
