Protective domain name service (PDNS) protects organisations by:
- blocking access to known malicious domains
- preventing data exfiltration through domain name system (DNS) requests
In an organisation that uses PDNS, devices send DNS queries to the PDNS service. PDNS checks the requested domain against its threat intelligence database. If the domain is safe, the request proceeds as usual. If the domain is flagged as malicious the request is blocked and you cannot access it.
PDNS designed for schools
Schools can apply for PDNS through their local authority, multi-academy trust, or directly through the NCSC.
PDNS for SchoolsThe initiative has a specialised version of the service to protect schools from online threats. PDNS supports schools by:
- blocking harmful content, preventing access to phishing sites, malware, and other cyber threats that could compromise school networks
- supporting safeguarding policies, helping schools comply with Keeping Children Safe in Education guidelines by restricting access to inappropriate and harmful content
- reducing cyber risks by protecting against ransomware attacks and data breaches
- minimising IT overhead: it requires no additional hardware and integrates with existing school networks
