Cybersecurity considerations for government communications teams

In an age where digital communications are central to citizen engagement, government communications teams face increasing scrutiny, not just over what they say, but how securely they say it. From targeted phishing attacks to the ever-present risks of data breaches, the threats are real, and the consequences, legal, reputational, and operational are significant. 

This post explores key cybersecurity considerations for government communications professionals, focusing on GDPR compliance, domain authentication, and data sovereignty. Three pillars essential for building trust and maintaining security in the public sector. 

1. GDPR: Privacy by design 

The General Data Protection Regulation (GDPR) is more than a compliance checkbox; it's a fundamental obligation to protect the privacy of citizens’ data. For communications teams, this means: 

• Lawful Basis for Communication: Every email campaign or newsletter must have a valid legal basis under GDPR, typically consent or legitimate interest. Consent must be freely given, specific, informed, and unambiguous. 

• Data Minimisation: Only collect and store data that is absolutely necessary for communication purposes. 

• Retention Policies: Ensure personal data is not kept longer than necessary and that unsubscribe requests are honoured promptly. 

• Processor Due Diligence: If you're using third-party platforms (like email service providers or survey tools), you must ensure they are GDPR-compliant and have appropriate data processing agreements in place. 

Risk to avoid: Using outdated or insecure platforms that lack adequate data protection measures. If a breach occurs, under GDPR, government organisations can face severe penalties—not to mention loss of public trust. 

2. Domain authentication: Securing the Government brand 

One of the most common and damaging threats to government communications is email spoofing. When bad actors impersonate government domains to send phishing emails. This is preventable with proper domain authentication protocols: 

• SPF (Sender Policy Framework): Verifies that an email is sent from an authorised mail server. 

• DKIM (DomainKeys Identified Mail): Adds a digital signature to messages to verify that they haven’t been altered. 

• DMARC (Domain-based Message Authentication, Reporting & Conformance): Ties SPF and DKIM together and tells receiving servers what to do with unauthenticated emails (e.g., reject, quarantine). 

Implementing SPF, DKIM, and DMARC on your domain is essential to prevent impersonation and to protect the credibility of official communications. Many UK government domains now publish DMARC policies at enforcement (p=reject) - a sign of strong email hygiene. 

Risk to avoid: Failing to set up or monitor DMARC policies. Without this, malicious actors can spoof your domain and spread misinformation or malware in your name. 

3. Data sovereignty: Keeping UK citizen data in the UK 

Public sector bodies are subject to strict requirements around data sovereignty. The principle that data is subject to the laws of the country in which it is collected and stored. For UK government communications teams, this means: 

• Choosing UK-based or UK-compliant data processors: Ensure any platform storing or processing citizen data complies with UK GDPR and stores data within the UK or an approved jurisdiction. 

• Avoiding transfer risks: If using cloud services, verify that data is not transferred to countries with inadequate data protection frameworks unless proper safeguards are in place (e.g. standard contractual clauses or binding corporate rules). 

• Audit your supply chain: Even if your primary platform is UK-based, check if it uses subprocessors located overseas. 

Risk to avoid: Hosting citizen data with providers that store or route data through jurisdictions outside the UK or EU without adequate safeguards, which may constitute a breach of data protection laws. 

Final thoughts 

Cybersecurity isn’t just an IT concern; it’s a core part of effective and ethical communication in government. By embedding privacy principles, securing your email domains, and ensuring data stays within compliant jurisdictions, communications teams can protect both their citizens and their organisations. 

Trust is earned through transparency and security.  

In today’s digital landscape, the way you protect data is as important as the message you send.
