The dependence on these cloud applications are great for productivity, but are not-so-great when it comes securing it. **Here are some quick facts:** **25%** of phishing emails bypass Office 365 Security **55%** of employees admit to clicking on links they don’t recognize **58%** of company (sensitive) data is stored in 365 documents. Microsoft’s infamous cloud suite is known to have been under attack from hackers as they found O365 accounts to be easy targets due to the lack of security protocols. "*Researchers from Barracuda Networks have found that hackers are targeting Microsoft Office 365 accounts with a worrying degree of success.*" Forbes 2019 | **[Microsoft Office 365 Accounts Under Attack -- What You Need To Know](https://www.forbes.com/sites/daveywinder/2019/05/02/microsoft-office-365-accounts-under-attack-what-you-need-to-know/#6ba9664d36cd)** #### ExchangeDefender’s solution – [Cloud App Security](https://exchangedefender.com/cloud-security-o365) Protect Office 365 applications with [advanced multi-layered security](https://exchangedefender.com/cloud-security-o365), and explore how our solution defends your digital workplace against cyber-threats.
