Domain Security Report 2026
Download CSC’s latest Domain Security Report, based on analysis of the Forbes Global 2000 and the world’s top 100 unicorns. Explore how companies are securing their domain ecosystems—and where threats and vulnerabilities remain. You’ll also learn how malicious third parties are exploiting weaknesses like phishing, DNS hijacking, domain portfolios, and the external attack surface.

As AI-powered cyberattacks rise, domains and DNS remain one of the most common entry points for domain-based threats. That includes DNS hijacking, domain spoofing, and phishing campaigns.
Our Domain Security Report 2026 explores how the Global 2000 and leading unicorns are adopting key security measures like DMARC, DNS redundancy, registry locks, DNSSEC, and CAA records.
It highlights regional and industry performance, registrar-related risks, and the scale of suspicious domain activity targeting global brands. It also shows why continuous domain monitoring is a critical defense strategy.
The findings reveal uneven levels of security maturity. While more companies are strengthening email authentication, many still lack the resilience needed to protect critical domains from growing global cybersecurity threats. The report goes on to explain where progress is being made, where gaps remain, and what enterprise organizations should prioritize to strengthen their security posture.
What you'll discover
How unicorns compare to the Global 2000
Unicorns show strong adoption of DNS-record-based controls. But they fall behind on resilience and registrar choice.
-
Unicorns outperform the Global 2000 in five out of eight key security measures, including SPF, DKIM, DMARC, DNSSEC, and CAA records.
-
DMARC adoption reaches 96% among unicorns, compared to 79.8% among the Global 2000.
-
Only 1% of unicorns use DNS redundancy, and almost 90% rely on a single cloud infrastructure.
Where domain security is strengthening—and where it’s slipping
Adoption of key controls is inconsistent.
-
DMARC continues to rise quickly, driven by regulations like NIS2 and increased phishing activity—a top cybersecurity threat for enterprises.
-
DNS redundancy continues to decline as companies consolidate infrastructure in the cloud without true dual-network resilience.
-
DNSSEC and CAA record adoption have increased significantly since 2020. Yet they remain at just 11% across the Global 2000.
The greatest areas of risk for global brands
Risk exposure varies sharply by region, industry, and malicious domain activity.
-
APAC shows strong year-on-year improvement. But it still trails more than 15 points behind EMEA and the Americas in overall adoption.
-
67% of Global 2000 companies have implemented fewer than half of CSC’s recommended domain security measures.
-
88% of homoglyph domains containing Global 2000 brand names are owned by third parties. 40% of these domains have MX records, which enable attackers to phish and intercept emails.
