Office 365



Many organisations have migrated to Office 365 or are considering making the move, however, it is impossible to replicate the same level of protection and reliability of onpremise systems by using a single cloud service provider. The decision to move to the cloud can be both daunting and challenging, with compliance requirements, business continuity plans, constantly evolving threats and the need to ensure your organisation has an undisrupted email service. All of these security and compliance issues cannot be resolved with a single vendor solution, so many organisations are using third party service such as Topsec to fill in the gaps.


When using Topsec Email Security in conjunction with Office 365, your organisation uses our comprehensive Topsec Email Security (anti-virus, anti-spam and content policy) service as its first line of defence. The delivery of mail is then sent to Office 365. Office 365 uses Microsoft Exchange which provides 50GB of email storage for each user, contacts and calendar sharing with access from any device. Together, Topsec Email Security and Office 365 provide the complete cloud solution for your email, giving you the control to manage and secure your email without the burden of maintaining the underlying infrastructure. Your organisation will have a dual Email Continuity solution which will ensure that you are never without email or the ability to send and receive emails. This is achieved by site resilience within the Microsoft Environment and also with Topsec Email Continuity. Also, Topsec Blended Threats gives your organisation added IT security by mitigating against the risks of Phishing, Ransomware, Cryptolocker and other Malware attacks.


The MX records for a specific domain are configured to send mail to Topsec’s inbound SMTP servers. The Topsec Email Security service filters the mail and sends the clean mail to Office 365. Office 365 using Microsoft Exchange routes the specific email to end user’s mailbox. Users access their mail via Office 365 using Outlook, Outlook Web Access or their mobile device using ActiveSync.
