The Online Safety Act is here, and its impact is far-reaching for any digital service operating in the UK.
The Act represents a major shift in the way online platforms must manage safety, risk, and user accountability.
In this article, we’ll explore the act, how it will impact IT leaders and businesses that operate in the UK as well as the additional risks the act introduces.
What is the UK Online Safety Act?
The UK Online Safety Act is a new set of laws implemented across the United Kingdom aimed at protecting both children and adults online.
The laws establish legal precedent that places responsibility on to online service providers to protect users from content deemed ‘harmful’.
Ultimately, the act aims to make online safety more effective by forcing accountability onto organisations rather than individuals.
Though online coverage has focused on adult content sites, the act applies broadly across major social media giants and search engines as well as user-to-user services, file-sharing platforms, gaming sites and dating apps.
Platforms must proactively assess risks and implement systems to detect and remove illegal content. Organisations that fail to do so could face fines up to £18 million or 10% of global annual turnover, whichever is greater.
Platforms must also implement “highly effective” age assurance systems to protect under‑18s from accessing content intended for adults.
How will the UK Online Safety Act Impact IT Leaders?
While the act's intentions are clearly to foster a safer online environment, it has been criticised across the tech industry.
Its implementation brings a complex web of technical, operational, and ethical challenges for digital businesses, particularly regarding user privacy and end-to-end encryption.
Messaging platforms like WhatsApp, Signal, and Element have raised alarms that the Act could force platforms to scan private messages both personal and on a business level. This undermines secure communication, and some suggest this is a dangerous precedent for mass surveillance.
For IT and security leaders, this isn’t just a question of safety; it's a fundamental challenge to the very architecture of secure communications.
Introducing accredited technology or client-side scanning, if mandated for end-to-end encrypted services, would mean many organisations have to begin a complete re-engineering of security protocols
This creates a 'backdoor' vulnerability that, once established, could be exploited by malicious actors.
It forces a difficult choice for tech leaders, whether to compromise a core security principle or potentially withdraw services from the UK market.
The UK government has stated it would only use its ability to read messages powers when "technically feasible," critics argue this vague wording leaves the door open for intrusive mandate.
A key aspect of the UK Online Safety Act that is likely to impact online organisations is through the administrative burden of increased compliance.
- IT leaders will be at the forefront of implementing these new mandates. This involves:
- Developing robust continuous risk assessment frameworks for all content on their platforms, requiring dedicated analytical resources.
- Scaling content moderation, usually by investing in advanced AI-driven content detection tools, alongside a significant increase in human moderation teams. This demands expertise in natural language processing, computer vision, and the development of intricate content policies.
- Deploying 'highly effective' age verification solutions (e.g., facial age estimation, digital id checks) and ensuring these are both accurate and privacy-compliant (a significant data protection challenge in itself).
- Enhanced data management as the act mandates greater transparency and reporting to OFCOM. This will require robust data collection, analytics, and secure reporting pipelines. This also intersects heavily with GDPR compliance, as content moderation often involves personal data.
New Risks To Business From Online Safety Act
From risk assessments, content moderation, user reporting tools, and age-assurance mechanisms, the new rules place immense pressure on startups and SMEs, who may lack the resources of tech giants like Meta or Google.
There is a real threat that the rules could stifle innovation and competition from new players.
Building 'safety by design' from the ground up, as the act demands, is incredibly resource-intensive. This could create a higher barrier to entry in the UK digital market, favouring the tech giants who already have vast legal, technical, and financial resources.
It raises concerns that the UK, once a hub for digital innovation, might see a slowdown in new service launches or even market withdrawals by companies unable or unwilling to bear the compliance burden.
Beyond the direct mandates, IT leaders must consider the additional cybersecurity risks. Age verification systems involve collecting sensitive biometric or identity data - these are incredibly attractive targets for cybercriminals, creating new 'honeypots' of personal information.
Similarly, any mandated 'scanning' of encrypted communications, even if presented as privacy-preserving, could introduce complex software vulnerabilities that expose all users to greater risk.
The new mandates also create a new layer of managing different digital regulations in different regions, layering with differing laws both across Europe and globally
Organisations IT and legal teams will need to work in tandem to navigate this complex combination of international laws, ensuring compliance across jurisdictions without conflicting requirements.
The UK Online Safety Act, though it may evolve, is here to stay. It signals a significant shift that one that puts platform accountability.
Despite its important online safety goals, the act’s’ execution presents significant operational challenges that tech leaders can’t ignore.
Now is the time to reassess your platform architecture, compliance strategy, and risk posture. Because the future of online safety isn't just about protecting users, it's also about protecting your business.
