DNS is the foundation of everything your customers reach — and a favourite attacker target. QSECS reviews your DNS configuration, DNSSEC, email-authentication records and subdomain exposure to close the gaps that enable spoofing, takeover and interception.
We assess your DNS estate for the misconfigurations attackers exploit to impersonate, intercept or hijack.
DNS quietly underpins every service your customers and staff reach, which is exactly why attackers target it. Misconfigured records, missing DNSSEC and weak email authentication enable spoofing, interception and domain takeover.
QSECS reviews your entire DNS estate — including the forgotten and third-party-managed records that sprawl over time — and closes the gaps that let attackers impersonate your brand or hijack your subdomains.
DNS configuration hygiene — zone setup, record sprawl and information leakage
DNSSEC validation to protect against cache poisoning and spoofing
Email authentication — SPF, DKIM and DMARC alignment to stop domain spoofing
Subdomain-takeover exposure from dangling records pointing at unclaimed services
Resolver, registrar and zone-transfer settings that expand your attack surface
DNS Trust Is on the Quantum Clock
DNS and DNSSEC rest on digital signatures — precisely the cryptography quantum computers are projected to forge. Executive Order 14412, "Securing the Nation Against Advanced Cryptographic Attacks," now mandates that federal systems move to post-quantum cryptography, with key establishment by December 31, 2030 and digital signatures by December 31, 2031. Validating that your DNS records, signing keys and resolvers stay trustworthy as standards shift is a moving target, not a one-off audit. QRedSentinel keeps your DNS posture under constant watch, so signing-key and resolver weaknesses surface in hours rather than at the next review.
We turn a sprawling, often-forgotten DNS estate into a hardened, monitored asset.
We enumerate your full DNS footprint, including forgotten and third-party-managed records
We test for active spoofing, poisoning and takeover paths rather than reporting theory
We provide exact record-level fixes for SPF, DKIM, DMARC and DNSSEC
We prioritise dangling records and takeover risks that can be weaponised immediately
We recommend monitoring so future DNS changes don't silently reopen exposure
