According to the UK’s Department for Science, Innovation & Technology ‘Cyber Security Breaches Survey’ carried out in the winter of 23/24, the most common type of attack remains phishing. A whopping 70% of medium-sized businesses and 66% of high-come charities (£500k+ in annual income) report some form of cyber security breach or attack in the preceding12 months.
Whilst ensuring we educate our staff is critical to avoiding these attacks, rising frequency of these attacks and lapses in concentration do occur and can prove costly. The estimated costs to medium and large businesses is £10,830. This of course, does not include the high-costs of reputational damage.
Enhancing email security provides numerous benefits that protect both individuals and organisations from a wide range of threats. Given the critical role email plays in communication and the sharing of sensitive information, improved email security helps safeguard data, ensure business continuity, and build trust.
Key benefits of enhancing email security:
- Protection Against Phishing Attacks
Phishing attacks, where malicious actors impersonate trusted entities to steal sensitive information (such as login credentials, financial information, or personal data), are one of the most common email threats. Enhancing email security helps:
– Identify and block phishing emails before they reach users.
– Reduce the risk of data breaches and financial losses caused by employees clicking on malicious links or attachments.
– Educate users through security awareness training, helping them recognise and avoid phishing attempts.
- Preventing Malware and Ransomware InfectionsMalware, including ransomware, is often delivered via email attachments or links to compromised websites. Enhanced email security solutions provide:– Real-time scanning and filtering of email attachments and URLs to detect and block malicious content.– Prevention of malware infections that could cripple operations, lock critical systems, or demand ransom payments.– Reduced risk of sensitive data being encrypted, leaked, or destroyed by malicious software.
- Data Loss Prevention (DLP)Email security solutions with Data Loss Prevention (DLP) capabilities ensure that sensitive or confidential information is not accidentally or intentionally sent outside the organisation. Benefits include:– Monitoring outgoing emails for sensitive data such as personal information (e.g., Social Security numbers), intellectual property, or financial data.– Blocking unauthorised sharing of confidential files or information to external recipients.– Ensuring compliance with regulations such as GDPR, HIPAA, and other data protection laws by preventing data leaks.
- Safeguarding Against Business Email Compromise (BEC)Business Email Compromise (BEC) is a highly targeted attack where hackers impersonate company executives or trusted contacts to trick employees into making unauthorised transfers or sharing confidential information. Enhanced email security can:– Detect and block fraudulent emails that attempt to spoof executives, vendors, or partners.– Use artificial intelligence and machine learning to identify unusual communication patterns or suspicious requests.– Provide extra layers of authentication (such as multi-factor authentication) for critical transactions to prevent financial fraud.
- Improved Spam FilteringA strong email security system includes advanced spam filtering, reducing the clutter of unwanted or unsolicited emails in users’ inboxes. The benefits of better spam filtering include:– Increasing productivity by minimising the time spent managing and deleting spam emails.– Reducing the likelihood of malicious spam containing harmful attachments or links reaching employees.– Enhancing the overall efficiency of email systems by reducing the load caused by processing large volumes of spam.
- Increased Compliance with RegulationsMany industries and countries have strict regulations governing the use and protection of sensitive information, such as the GDPR, HIPAA, PCI DSS, and more. Enhanced email security helps:– Ensure that sensitive data transmitted via email is encrypted and secure.– Provide audit trails and reporting capabilities to demonstrate compliance with data protection laws and regulations.– Avoid costly penalties and legal liabilities associated with data breaches or non-compliance.
- Strengthened Email Authentication (DMARC, DKIM, SPF)Enhanced email security protocols such as DMARC (Domain-based Message Authentication, Reporting & Conformance), DKIM (DomainKeys Identified Mail), and SPF (Sender Policy Framework) authenticate emails from trusted senders. The benefits of stronger email authentication include:– Reducing the risk of email spoofing, where attackers forge email headers to appear as if they are coming from legitimate sources.– Protecting the organisation’s brand and reputation by ensuring customers and partners receive authentic communications.– Providing visibility into unauthorised use of your email domain and helping prevent domain hijacking
- Mitigating Insider ThreatsEmail security solutions can help mitigate insider threats, whether they are accidental or malicious. Benefits include:– Monitoring and controlling email usage to detect suspicious activity from employees, contractors, or third parties.– Identifying unusual email behaviours, such as large attachments being sent to external addresses, that could signal data exfiltration.– Providing security measures like encryption and rights management to ensure that sensitive data is only accessible to authorised individuals.
- Maintaining Business ContinuityEmail is a critical communication tool, and disruptions can have a significant impact on business operations. Enhanced email security helps:– Ensure that email systems remain functional and available, even during attempted cyberattacks.– Provide email backup and recovery options in case of accidental data loss or ransomware incidents.– Minimise downtime and business disruptions by quickly identifying and resolving email-related security incidents.
- Protection of Intellectual PropertyFor many organisations, intellectual property (IP) is one of the most valuable assets, and email is often used to share proprietary information. Enhanced email security ensures:– Confidential information, trade secrets, and intellectual property are protected from unauthorised access or theft.– Emails containing sensitive IP are encrypted to prevent interception during transmission.– Proper access control mechanisms are in place to limit who can view, share, or forward sensitive information.
- Enhanced Trust and ReputationA data breach or email compromise can severely damage an organisation’s reputation. By enhancing email security, organisations can:– Build trust with customers, partners, and stakeholders by demonstrating a commitment to security and privacy.– Protect the brand from negative press and financial losses resulting from a published data breach or phishing attack.– Provide peace of mind to customers who are sharing personal information or conducting business via email with the organisation.
- Improved Collaboration and Remote Work SecurityAs remote work and cloud-based collaboration increase, securing email becomes even more critical for distributed teams. Benefits include:– Ensuring secure email communications for remote workers, preventing unauthorised access to sensitive data from insecure networks.– Supporting secure collaboration through encrypted emails and file-sharing mechanisms.– Providing mobile device management (MDM) capabilities to secure email access from smartphones and tablets.
- Cost SavingsInvesting in enhanced email security can lead to significant cost savings by preventing expensive security incidents. Benefits include:– Reducing the risk of costly ransomware attacks, data breaches, and associated legal penalties.– Avoiding financial losses from fraudulent activities like Business Email Compromise (BEC) scams.– Lowering operational costs by reducing spam, phishing, and malware-related IT support and recovery efforts.
