“Reliable DMARC Solution with Excellent Support”

Tom Glavas, Owner of S-IT

Overview

Company: S-IT

Customer Type: MSP Partner

Country: Belgium

S-IT, a trusted Managed Service Provider (MSP) led by Tom Glavas, offers comprehensive cybersecurity solutions to organizations of all sizes. Like many MSPs, S-IT recognized the growing threat of email-based attacks and the increasing importance of email authentication. In search of a solution that could enhance domain security while remaining scalable across multiple clients, S-IT partnered with PowerDMARC. 

The Challenge

S-IT faced several challenges around email security and domain spoofing, both for its internal operations and client domains. Key issues included:

  • Lack of visibility into how domains were being used or misused by unauthorized actors.
  • Difficulty managing and enforcing DMARC, SPF, and DKIM across multiple domains.
  • Manual monitoring processes that were time-consuming and prone to error.
  • The need for real-time insights to detect and act on phishing threats promptly.
  • A desire for a scalable solution that could be integrated into S-IT’s MSP offerings.

The Solution

PowerDMARC’s MSP Partner Program helped S-IT deploy a multi-tenant platform to gain centralized visibility and control over domain authentication. Key elements of the implementation included:

  • Automated DMARC, SPF, and DKIM management, with clear guidance through each setup step.
  • Access to a powerful dashboard that displays real-time email traffic, alignment issues, and authentication failures.
  • Detailed forensic and aggregate reports that help quickly identify unauthorized use of client domains.
  • Multi-domain support with client-level segmentation to simplify MSP service delivery.
  • Responsive and knowledgeable technical support during onboarding and ongoing use.

The Result

The impact of partnering with PowerDMARC was measurable. S-IT clients reported: 

  • Significant reduction in spoofing and phishing attempts using their domain names.
  • Improved deliverability for marketing and business emails due to stronger sender reputation.
  • Faster onboarding for new clients, with automated DMARC rollout and monitoring.
  • Increased confidence in S-IT’s ability to manage email security threats.

By partnering with PowerDMARC, S-IT successfully transformed a complex, manual process into a streamlined, automated, and secure system for managing email authentication. Today, they offer clients improved protection, visibility, and compliance without the usual overhead.
