Phishing Protection and Spear Phishing Defense for Businesses

Phishing is the most common cause of data loss and financial damage in businesses. Conbool MailGuard detects phishing emails, spear phishing, and manipulated links before they reach your employees.

The three most dangerous email threats

Phishing

Fake emails that trick employees into revealing credentials or downloading malware. Often deceptively realistic.

Credential Phishing

Fake login pages that steal credentials. Whether Microsoft 365, VPN, or banking: credential phishing is the most common attack type.

Spear Phishing

Targeted attacks on individuals with personalized content. Traditional spam filters often fail to detect these emails.

How Conbool MailGuard stops phishing

Multiple protection layers work together so no phishing email gets through.

Sender Verification

MailGuard checks SPF, DKIM, and DMARC on every incoming email. Forged sender addresses are immediately detected and blocked.

Link Protection (URL Rewriting)

All links in emails are checked in real time when clicked. Even if a URL becomes malicious after delivery, your employees are protected.

Sender Anomaly Detection

MailGuard detects forged sender addresses and suspicious sender patterns. Display name manipulation, missing authentication, and mismatched reply-to addresses are immediately flagged.

Phishing Attachment Quarantine

Attachments in phishing emails are automatically isolated and moved to quarantine. For comprehensive attachment protection with CDR technology, see our Email Attachment Protection solution.

Header Analysis

MailGuard analyzes technical email headers for anomalies: unusual routing paths, missing authentication, or suspicious relay servers.

Quarantine with Context

Suspicious emails land in quarantine with a clear explanation of why they were blocked. No guessing, no risk.

Why awareness training alone isn't enough

Training is important. But people make mistakes, especially under time pressure. MailGuard is the technical safeguard.

People click

Studies show: Even after training, 4 to 8% of employees click on phishing links. One click is enough.

Attacks are getting better

AI-generated phishing emails are nearly indistinguishable from real emails. Technical detection is faster than human judgment.

24/7 protection

MailGuard doesn't sleep, isn't on vacation, and doesn't have a stressful day. Every email is checked with equal care.

Compliance evidence

GDPR and NIS2 require technical protection measures. Awareness alone doesn't meet the requirements.

FAQ

What's the difference between phishing and spear phishing?
Phishing is a mass attack with generic emails to many recipients. Spear phishing is a targeted attack on a specific person with personalized content, such as the victim's name, position, or current projects.
What's the difference between phishing and credential phishing?
Classic phishing relies on mass distribution and generic content. Credential phishing specifically targets login credentials, often through fake login pages for Microsoft 365, Google, or VPN portals. MailGuard detects both variants through URL analysis and sender verification.
What is URL rewriting and why is it important?
URL rewriting replaces links in emails with secure redirects. When clicked, MailGuard checks the target page in real time. This also protects against links that become malicious hours after email delivery (delayed phishing).
Do I still need awareness training?
Yes, awareness training is a valuable complement. But it doesn't replace a technical solution. MailGuard catches the emails that would get through despite training.
Does phishing protection work with Microsoft 365?
Yes. MailGuard operates as an upstream gateway and complements Exchange Online Protection (EOP) and Microsoft Defender for Office 365.
How many phishing emails does MailGuard detect?
MailGuard combines sender validation via SPF, DKIM and DMARC, link analysis with a reputation check at time of click, header inspection and content checks. Each stage feeds a score whose thresholds are configurable per tenant. The resulting detection rate depends on your mail volume and chosen policy, and can be measured up front in audit mode before anything is enforced.
