How many suspicious emails reach your team each week, and how many of them look convincingly real?
Email remains one of the most common entry points for cyber attacks. Even with modern security improvements, email is still a high-risk channel because it relies on people recognising threats and making the right decision under pressure.
Attackers use email to trick users into handing over sensitive information, clicking malicious links, or downloading infected attachments. Once a threat reaches an inbox, the risk increases dramatically.
Why Email Is a Major Risk for Businesses
Email is one of the oldest widely used technologies on the internet. That history brings a major downside: it was not built with modern security threats in mind.
Common email-based threats include:
- Phishing attempts designed to steal passwords and data
- Malicious links that lead to fake login pages or downloads
- Infected attachments carrying malware or ransomware
- Impersonation attacks pretending to be a colleague, supplier, or director
What Advanced Email Filtering Does Differently
Basic spam filtering is useful, but it is not enough on its own. Advanced email filtering goes further by analysing sender identity, message patterns, links, and attachments to catch threats that look legitimate.
At Carden IT Services, advanced email filtering and threat detection is designed to block threats before they ever reach your users.
Key Email Filtering Protections Your Business Needs
| Protection | What It Detects | Why It Matters |
|---|---|---|
| Impersonation Detection | Emails pretending to be from someone inside your organisation | Reduces fraud risk and prevents internal trust being exploited |
| Domain Similarity Checks | Lookalike domains designed to trick recipients | Stops “almost identical” sender addresses used in scams |
| Attachment Analysis | Malicious files and suspicious attachment behaviour | Blocks malware and ransomware before it is opened |
| Cloud Sandbox Viewing | Suspicious emails that need safe verification | Allows checking content without risking infection |
How Threat Actors Use Email to Bypass Security
Modern phishing emails are often well written and carefully targeted. Attackers may research your business, reference real names, and imitate internal writing style to create believable messages.
Common tactics include:
- Pretending to be a CEO requesting an urgent transfer or confidential document
- Impersonating IT support to request passwords or MFA codes
- Sending “invoice” attachments to trigger malware installation
- Creating emails that pressure users to act quickly without verification
Why a Cloud-Based Sandbox Reduces Risk
Even with strong filtering, some emails will be borderline. You may need to confirm whether a message is legitimate before releasing it.
A cloud-based sandbox allows suspicious emails to be opened in a safe environment away from your network. If the message is genuine, it can be released. If it is malicious, the threat is contained and your network remains protected.
