The methods used by cyber criminals to gain unauthorised access to systems and data are becoming more sophisticated by the day. According to GOV.UK, phishing is the most common method of cyber-attack, with between 75% and 90%, of targeted cyber-attacks beginning with an email. Hackers are using ever more clever techniques, such as automation and fraudulent emails to socially engineer their way onto a network. Emails that contain malware and suspicious links are all common threats to SMEs with hackers targeting unprotected business email accounts to deceive employees and dupe people into handing over money and data, either by asking them to follow a malicious link or posing as another person (usually a stakeholder).

Email Security Services to Protect your Email Environment

With emails being one of the main methods of communication in the workplace, and with the alarming increase of cyber security breaches, particularly through phishing attacks, ensuring robust email security is vital for organisations of all sizes. The government’s Cyber Security Breaches Survey showed that 93% of large businesses and 84% of medium businesses reported phishing attacks in 2023. But despite the very real threat that phishing poses to businesses today, almost 1 in 5 organisations only deliver phishing awareness training to their employees once per year.

Businesses use email hosting platforms such as Office 365 to send and receive large volumes of highly sensitive personal information, because of this cyber criminals frequently exploit email as the primary method for malicious activities. Emails serve as an avenue to gain unauthorised access to data, conduct phishing attacks, hold companies to ransom, and deploy harmful malware. Therefore, safeguarding this data from hackers is crucial.

Anti-spam services have become critical aspects of an SME’s IT network and SaaS portfolio in the fight against malware. Office 365 has a built-in level of anti-spam technology, providing a base layer of protection for users of Exchange Online. Complete Email Security for Microsoft 365 will boost your company’s defences against unwanted emails. Using Barracuda Sentinel technology, which detects threats that traditional email security systems cannot. By integrating with Exchange Online, it detects attacks coming from both internal and external sources, using AI to detect malware within every email sent to and from your organisation’s exchange server.

The implementation of robust email security not only ensures data security but also aids in compliance with industry regulations and legal requirements. Acting as a safeguard for an organisation’s reputation by preventing email spoofing, scams, and other fraudulent activities. By ensuring communication integrity, mitigating insider threats, and preventing data loss, email security provides a resilient and secure digital environment for all users.

Core Features of our Complete Email Security Services

Spear Phishing Prevention

Spear phishing, a targeted form of cyber threat, often exploits personalised information to deceive individuals within an organisation. Our email security service automatically detects and prevents spear phishing attacks. The AI engine learns each organisations’ unique communication patterns and then leverages these patterns to identify anomalies and quarantine spear phishing attacks in real-time. Our email security services not only provide immediate protection against known threats but also serve as an evolving shield against emerging and sophisticated phishing attempts. By continuously learning and adapting, the AI engine ensures that organisations can confidently navigate the digital landscape, safeguarding their communication channels from the invasive risks associated with spear phishing attacks.

Detection of Employee Impersonation

Our email security system is equipped with advanced capabilities for the detection of various forms of employee impersonation, providing a comprehensive defence against cyber threats. Employee impersonation, a tactic commonly employed by malicious actors, poses a significant risk to organisational security. By detecting any type of employee impersonation, including the impersonation of executives, our solution is designed to proactively identify and neutralise these threats. It can detect spoofed emails, typo-squatted domains, and phishing emails sent from free or personal email accounts, ensuring the integrity of organisational communication channels.

Stop Zero Day Phishing

Our email security services halt zero-day phishing attacks by going beyond traditional security measures, employing advanced techniques to identify and neutralise threats that would otherwise emerge without prior detection. Zero-day phishing attacks are characterised by their unpredictability and novelty, they exploit vulnerabilities before security systems can develop countermeasures. Our comprehensive approach ensures that organisations are protected against these emerging threats, providing a robust defence mechanism for every eventuality.

Detection of Web Impersonation

We recognise the increasing sophistication and success rates of attacks that impersonate trusted web services such as DocuSign and Dropbox. Email-based impersonation of platforms such as these poses a significant threat, as these attacks often display an alarming level of realism in their appearance, language, and overall presentation. This realism makes it challenging for individuals to tell the difference between authentic communications and malicious attempts, increasing the likelihood of falling victim to phishing schemes, data extraction, or other harmful activities.

Our solution is designed to identify and thwart such deceptive tactics, bolstering the resilience of organisations against cyber threats. It provides a crucial layer of defence, safeguarding against the potential compromise of sensitive information and maintaining the trustworthiness of communication channels with widely used web services.

Investigate Inbox Rules

Understanding the subtle indicators of a potential security threat is vital to quickly addressing the threat. Changes to users’ inbox rules can indicate an account takeover. Our email security solution allows organisations to set up alerts triggered by the detection of changes to inbox rules. These alerts serve as an immediate notification, prompting the IT team to initiate a thorough investigation into the flagged activity. By leveraging timely alerts, organisations can swiftly respond to potential security incidents, mitigating risks associated with account takeovers and unauthorised access.

Detect Compromised Email

Within our email security service we employ technology to automatically discern and flag malicious emails originating from compromised accounts. The detection of these email accounts is a crucial line of defence against cyber threats, as attackers often exploit jeopardised accounts to perpetrate a range of malicious activities, from spreading malware to executing phishing campaigns.

By leveraging advanced technology and real-time analysis, our email security solution automatically identifies malicious emails sent from compromised accounts and flags them to administrators. This solution empowers organisations to stay one step ahead of potential threats, ensuring the integrity of email communications and safeguarding sensitive information from unauthorised access and misuse.

Benefits of Email Security Services

Data Protection

Effective data protection is crucial for organisations to remain in line with GDPR compliance. Email security plays a pivotal role in safeguarding sensitive business information, by incorporating measures such as encryption and access controls, it ensures that confidential data remains shielded from unauthorised access or potential data breaches. By adopting these safeguards, organisations increase their defences against external threats, preserving the confidentiality of critical and sensitive business data.

Prevention of Cyber Attacks

Email security services serve as the frontline defence against a number of cyber threats. Our email security service is adept at identifying and blocking phishing attempts, malicious attachments, and other cyber threats, significantly reducing the risk of successful attacks on the organisation’s network and systems. By proactively preventing cyber attacks through comprehensive email security, organisations can mitigate potential damage, protect sensitive data, and maintain the trust of their stakeholders.

Business Continuity

Implementing robust email security measures goes beyond safeguarding data; it also ensures business continuity. By mitigating the impact of email-related cyber incidents, organisations can avoid disruptions, ensuring uninterrupted communication and operations. This resilience is crucial for maintaining productivity and reputation, even in the face of evolving cyber threats.

GDPR Compliance

In an era of stringent data protection regulations, email protection is integral for achieving and maintaining compliance. Many industries are subject to specific data protection and privacy regulations, such as the General Data Protection Regulation (GDPR). Implementing email security measures helps businesses meet these compliance requirements, reducing the risk of legal consequences and financial penalties. This not only safeguards organisational data but also instils confidence among clients and partners regarding the responsible handling of sensitive information.

Cost Savings

Investing in robust email security services results in long-term cost savings for businesses. By reducing the likelihood of costly cyber incidents, data breaches, and the associated recovery expenses, organisations can effectively allocate resources and budgets. The preventive nature of email security not only safeguards against financial losses but also contributes to overall operational efficiency and sustainability.

Secure File Sharing

Our advanced email security solutions offer secure file-sharing capabilities, enhancing collaboration within organisations. Employees can share sensitive documents internally or with clients in a protected and encrypted manner. This feature not only ensures the confidentiality of shared information but also fosters a secure and efficient exchange of critical files, reinforcing the overall security posture of the organisation.

What is a Zero Day Attack?

A zero-day attack is an unknown security vulnerability that cyber criminals will leverage to gain access to systems and data. These attacks will not be picked up by anti-virus alone.

It refers to a cyber attack executed by cyber criminals who seek to capitalise on a previously unknown software flaw and gain unauthorised access to systems and sensitive data. The term “zero-day” implies that the attack occurs on the very same day that the vulnerability is discovered or exploited, leaving organisations with zero days of preparation or defence.

These attacks are particularly dangerous because they target vulnerabilities that have not yet been identified or patched by the software developers. This lack of prior awareness leaves organisations vulnerable to exploitation, as there are no pre-existing email security measures or fixes in place to counteract the attack. As a result, traditional antivirus solutions, which rely on known signatures and patterns to identify threats, often prove ineffective against zero-day attacks.

To counter the threat posed by zero-day attacks, organisations must adopt proactive security measures. Prompt and regular software updates, as well as collaboration with security experts such as CIT, play a pivotal role in mitigating the risks associated with these elusive and rapidly evolving cyber threats. Understanding the nature of zero-day attacks is essential for organisations to bolster their cyber security defences.
