Email Security

  • Introduction

    What Is Email Security?

    Email is one of the primary means of communication between businesses and customers. Email security uses different techniques for keeping sensitive information in email and accounts secure. GDPR requires all companies to protect personal data in all its forms which is why it's important to have a secure email solution.

    Why You Need Email Security?

    With businesses communicating more through email the usual baggage of people are trying to exploit this through different types of attack:

    • Spam – unwanted email, usually unsolicited trying to sell things or entice users.
    • Phishing – socially engineered email trying to trick a user into sharing details by claiming to be from a trusted source when it isn’t, usually something like an email claiming to be from the taxman or from the bank needing the recipient to re-enter their details by clicking a link to take them to a page that looks genuine but isn’t.
    • Spear Phishing – less random and more targeted form of phishing where the attacker has more detailed information about the recipient so can make a more focused attack that will likely have more success such as providing information that the recipient would assume has come from a trusted source such as a colleague or business partner.
    • Payload – attachments in emails that contain a security threat masquerading as something else such as an invoice that is a PDF file but that contains a computer security threat such as ransomware or viruses.
  • The solution

    Our Approach to Email Security

    The techniques used in email filtering will determine how effectively mail is routed. At The Silver Cloud Business we use a combination of the following techniques to help you achieve secure email:

    • Reputation-Based Email Filters - Attempts to stop spam or allow legitimate email by filtering out known spammers or approving trusted senders based on reputation databases.
    • Whitelisting - Gives businesses the capability to determine which senders they accept email from by adding them to a list.
    • Blacklisting - Provides businesses the opportunity to determine which senders they want to block email from by adding them to a list.
    • Anti-virus – Your antivirus protection will help stop new and existing viruses and other forms of malicious code entering your system.
    • Content Analysis – Gives businesses the ability to block an email based on the content. E.g. If a message contains certain words, the content filter can determine that it is a spam message. Another example is if the message contained an attachment and the business doesn’t want to let it through. 

    With such a large attack surface with email it is imperative to make sure it is secure with an email threat filtering solution that helps to prevent attack. We've helped countless businesses with email security in Wiltshire, Hampshire and Dorset and we can help yours too.

Featured Case Study

  • Sector / Charity

    Local Charity The Trussell Trust, Adopts Full Cloud Services in Salisbury


    Our Client 

    The Trussell Trust is a leading anti-poverty charity which supports a nationwide network of food banks. Together they provide emergency food and support to people locked in poverty and campaign for change to create a hunger free future where food banks are no longer needed. There are more than 1,200 food bank centres in the Trussell Trust’s network, roughly two thirds of all the food banks in the UK. The Trussell Trust supports these food banks to provide nutritionally balanced emergency food parcels to people in crisis who have been referred to them by advice agencies, GPs, schools, and others. Food banks also offer people support and guidance to help them resolve the crises they are facing.

    The Problem

    Inconsistent software across workstations and laptops, outdated servers and a need for a more flexible working environment

    The Trussell Trust was running a fully supported version of Windows server in a hypervisor environment with VM’s running Active Directory and Exchange 2010 and file shares.

    Workstations and laptops were running a mixture of Windows 7 and Windows 10 with Office 2010. A 2008 R2 terminal server was being used for remote access and was due to go out of support with Microsoft.

    The organisation wanted to get all IT systems, workstations, and laptops running supported software and the latest Microsoft Office applications.

    They also wanted to get away from the old version of Microsoft Exchange and move their files to the cloud and migrate into SharePoint to become less reliant on on-premise servers and remove the 2008 R2 Terminal server.

    The Solution

    Utilising the full suite of Microsoft Office tools to ensure consistency and efficiency 

    • A new Microsoft 365 tenant was created using the not-for-profit portal. AD Sync tool was installed into their on-prem environment and their Active directory was synced up with M365 in full hybrid mode.
    • Once all machines were upgraded, the email hosting on Exchange 2010 was migrated using the cutover migration process to cloud-based Exchange online. This was done with no email downtime for the users.
    • Once the mail was all cut over, the Exchange 2010 server was de-commissioned and switched off.
    • As soon as the Trussell Trust was able to proceed with the migration of files to SharePoint, this was done using the Microsoft SharePoint Migration Tool in a staged manner to avoid users not being able to access file shares.
    • Once each share was migrated it was made read-only on the on-premises systems for reference purposes only and to ensure continuity of data.
    • Microsoft Teams was also deployed during this stage to make every user experience much easier and more flexible.
    • The only exception to the SharePoint Migration was the Accounts files that were required to stay on-premises due to the accounting package in use. However, we were able to utilise the Direct Access system that was deployed earlier in the project to assist with remote access to this.

    The Outcome

    Fully supported and up-to-date in a Hybrid cloud environment

    The finished project meant that the organisation is now running its IT systems on fully supported software and operating systems, with the latest office applications in a Hybrid cloud environment. Staff are able to work much more efficiently moving forward with flexible working, with the majority of their systems fully cloud-based.
