Upcoming NCSC Mail Check Changes and the Best Alternative
March 6, 2025 | 2 min read
The UK’s National Cyber Security Centre (NCSC) is making major changes to its Mail Check service, set to take effect by March 24, 2025. These updates will result in the removal of essential email security features, including DMARC aggregate reporting, DKIM validation, and TLS monitoring. Organizations that rely on Mail Check must find an alternative solution to maintain email security and compliance.
This article explores what’s changing, how these updates impact your organization, and alternative solutions to ensure continued protection against phishing attacks.
What Is NCSC Mail Check?
NCSC Mail Check is a government service designed to help organizations improve their email authentication policies using protocols like DMARC, SPF, and DKIM. It provides domain owners with insights into email spoofing attempts and helps maintain secure email communication.
The tool is widely used by public sector organizations and security teams to enhance email security and prevent phishing attacks.
Why is DMARC reporting important for UK organizations
Domain-based Message Authentication, Reporting, and Conformance (DMARC) plays a vital role in safeguarding against phishing and email spoofing. By reviewing DMARC reports, organizations can:
- Detect and mitigate potential threats
- Safeguard their brand’s reputation
- Improve email deliverability
- Maintain trust with customers and partners
- Strengthen defenses against phishing attacks
How Do these Changes Impact UK Organizations
Loss of Email Authentication Visibility
Without DMARC reporting, organizations will struggle to detect unauthorized email activity, increasing the risk of phishing and domain spoofing.
Higher Phishing and Spoofing Risks
Without DKIM validation, verifying whether an email was legitimately sent from an authorized source becomes more difficult, making it easier for attackers to impersonate trusted domains.
Compliance and Security Gaps
Many organizations rely on Mail Check to meet security best practices. The removal of these features could lead to compliance gaps and increased exposure to email-based attacks.
Don’t Lose Your Defense
That’s why it’s crucial to ensure a smooth transition as quickly as possible, avoiding any security gaps.
Still want your email checked and protected against spoofing and phishing? We’ll keep you secure and worry-free before the Mail Check service ends on March 24th.
With NCSC Mail Check discontinuing key features, organizations must act now to maintain email security and compliance. Skysnag ensures a seamless transition with dedicated expert support, providing continuous domain protection and ensuring your emails reliably reach the inbox.
