Why You Need to Secure Your Business Email

Businesses and individuals use emails daily as an easy and convenient form of communication. However, with this convenience also comes some risks, particularly surrounding the security of sensitive information. One of the biggest concerns for businesses is the threat of phishing attacks. Unfortunately, these can lead to financial losses, data breaches and ultimately, reputational damage. This article explores the importance of securing your business email and why every business needs to do so.

Understanding Email Security:

Having email security in place protects confidentiality and integrity. Email Security uses technologies and protocols to detect and prevent various threats from cyber attackers. These include phishing, malware and spam. Effective Email Security solutions not only protect sensitive information but also ensure businesses remain compliant with regulatory requirements such as the General Data Protection Regulation (GDPR). (GDPR EU, 2024)

The Threat of Phishing Attacks:

Phishing attacks are one of the more common cyber threats that businesses face, with 32 million reported scams being recorded as according to as of May 2024 (NCSC.GOV.UK, 2024). These attacks normally involve an email that’s disguised as a legitimate message from a reputable source, such as a bank or a government agency. The aim of a phishing attack is to trick the victim into revealing sensitive information including bank details, login information etc. Depending on the severity of the sensitive information that is exchanged, phishing attacks can have severe consequences: financial loss, identity theft or unauthorised access to a business’s network to name a few.

Why Businesses Need Email Security:

Phishing being one of the more prevalent cyber threats, protecting business emails from this type of attack is paramount. According to an article by AAG-IT, Google’s ‘Gmail’ service blocks on average 100 million phishing emails a day. (AAG-IT, 2024) By investing in email security, businesses can protect their sensitive data, maintain customer trust and lower the risk of any possible financial loss due to a breach.

Key Features of Effective Email Security Solutions:

The key features of effective email security solutions are constantly evolving due to the ever-growing threat and increasing rate of cyber-attacks. Key features include enhanced spam filtering and protection against phishing attacks. Below are some of the main ones that are most effective to date:

  • Antivirus Scanning: Email Security will automatically scan incoming emails for malicious attachments and links, preventing possible malware infections.
  • Spam Filtering: Email Security will use algorithms to block any spam emails that come in, helping reduce phishing attempts.
  • Phishing Prevention: Email Security will use authentication protocols to verify that the sender email is authentic and block any spoofed emails, thus protecting business emails from phishing.
  • Transmission Encryption: Encrypts email data that is in transit, using protocols such as TLS. This will protect any sensitive information being sent and prevent interception from cyber attackers.
  • MFA (Multi-Factor Authentication): Adds another layer of security when logging in, requiring multiple forms of verification for access, such as SMS code, or by use of an authenticator app.
  • Employee Training: Employers can educate staff to recognise and respond to threats through training guides, creating a security aware culture.

The need to secure business emails cannot be overstated enough. Email Security measures are essential to protect sensitive information from phishing attacks, malware and spam. With the ever-increasing frequency of cyber threats and attacks, investing in Email Security to keep your company, and its data safe is crucial to modern-day working practices.
