Ensures swift recovery from ransomware attacks and improves business continuity
The best features Datto SIRIS offers are ease of use, competitive pricing, and great support, which stand out for me. The ease of use of Datto SIRIS comes from the all-in-one control panel, making it very easy to use and handy to have compared to other solutions I've used. Datto SIRIS has positively impacted my organization by improving business continuity; after a ransomware attack that took down our main server, using the bare-metal recovery, we were up and running within the day.
