PowerDMARC at it-sa 2026: Why DNS and Email Security Are SRE Essentials

PowerDMARC, a leading domain security and email authentication platform, has announced its participation in the prestigious it-sa Expo&Congress 2026 in Nuremberg, Germany. As Europe's largest IT security expo, the event highlights critical themes in secure data communication, threat defense, and identity management.

The SRE Angle: Why Email Security is an Infrastructure Metric

To many Site Reliability Engineers (SREs) and DevOps professionals, DMARC, DKIM, and SPF are often viewed solely as security or marketing concerns. However, SRE best practices dictate that reputation is a reliability metric. If transactional systems, automated alert relays, or customer notification systems fail to deliver emails because of misconfigured DNS records, it constitutes a severe service degradation.

Unintended modifications to DNS TXT records or domain expirations can disrupt email deliverability instantly. In modern cloud architecture, maintaining strict control over your domain's DNS zone file is just as important as monitoring container uptime.

How Rabbit SaaS Keeps Your Infrastructure Secure and Reliable

At Rabbit SaaS, we build tools that ensure your infrastructure is resilient, secure, and monitored from every angle:

• Domain Audit HQ: Prevents domain hijacking and misconfiguration disasters by proactively monitoring domain expiration dates, WHOIS records, and DNS changes. If an unexpected change occurs to your SPF, DKIM, or DMARC TXT records, Domain Audit HQ alerts you immediately so you can fix it before email deliverability drops.
• Certificate Guardian: Complements your domain security by ensuring all SSL/TLS certificates on your mail servers, APIs, and web apps are renewed on time, monitoring CT logs for rogue certificates.
• Status Navigator: If a DNS or mail delivery incident occurs, status pages hosted on Status Navigator keep your customers informed under your own brand, preserving corporate trust.

As organizations flock to events like it-sa to secure their perimeters, SREs must remember that keeping domains and DNS records healthy is the foundational first step of online trust.
