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
The Quantum Clock Is Ticking
Security experts estimate quantum computers capable of breaking RSA-2048 encryption could arrive by 2030-2035. Adversaries are already running "Harvest Now, Decrypt Later" campaigns — collecting encrypted data today to decrypt the moment quantum hardware matures. Every test we run is framed by that post-quantum reality, not just today's threats.
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
