Email Security in the home office

Which safety measures should be observed?

The coronavirus has been causing an increasing number of infections each day, which has resulted in drastic countermeasures. Shops, restaurants and other public places are closing, including offices.

For many companies, having employees work from home is the only way to protect their personnel while maintaining business operations. Both employers and employees are faced with major challenges as a result of this change. 

Dangers in the home office: hackers use times of crisis to launch targeted cyber attacks


The Hornetsecurity Security Lab has been observing various malicious email campaigns for several weeks now, which exploit the fear of the corona virus and aim to capture email addresses and passwords or to smuggle malware into the systems of the recipients through links and attached documents.

There is a danger that malware can enter the system with a single click, and it can be difficult to reach the in-house IT team  remotely.  When a large proportion of employees are working from their home offices, the servers for various communication platforms can become so heavily loaded that company-wide failures result.

The following precautions will improve IT security for your remote workforce


Office 365 users are targeted by cyber criminals, especially in such times of crisis. Security experts therefore recommend not relying solely on Microsoft’s protection mechanisms, but to additionally secure Office 365 accounts with third-party solutions. Protect your Microsoft Office 365 from advanced cyber attacks and  enjoy easy setup and intuitive operation that simplifies your IT security management.

When your employees are working remotely, it is especially important to protect against email server failures that can disrupt communication, as missing important emails will cause further complications in the company’s operations. This can be achieved with so-called Continuity Services, which effectively protect your email system from failures and thus guarantee the high availability of your email traffic.

The following additional measures can contribute to IT security in the home office and protect against cyber threats:


Checklist: Secure in the home office


  • Use of a VPN service
  • Install the latest updates for operating systems and apps
  • Restriction of access rights
  • Protect enterprise devices using appropriate security software — with data-erasure capabilities for devices reported lost or stolen, separation of personal and professional data, and restriction of app installation options
  • Employee training courses to raise awareness of cyber threats

Continuity Service: Receive emails reliably even in your home office


Contracts, important information and contact details are exchanged by email. However, if the company’s own email server goes down for an extended period, this is especially problematic in the current crisis situation where all employees are telecommuting. The support team is not on site as usual, and a long-term communication outage will create serious complications for business operations. It is therefore critical to have alternative solutions that can take over in an emergency so no emails will be lost and messages can still be sent and received.

The right solution: Continuity Service

Hornetsecurity’s Continuity Service is the right solution for this problem. It provides an autonomous monitoring system that detects when the customer’s mail server has failed and activates immediately. With Continuity Service running, the delivery of emails continues without interruption by alternative means (POP3/IMAP mailbox or webmail access). Access to secure emails is thus maintained even during an outage, for example, directly from Outlook.

365 Total Protection Suite – Cloud Security for Office 365


For many companies, Microsoft Office 365 is an ideal tool for continuing work from the home office during the Coronavirus crisis. However, this also means that vast quantities of highly sensitive data are loaded into the cloud and exchanged – something that cybercriminals will be happy to exploit.
