Capita Slammed With £14M Fine Over Massive 2023 Data Breach

On October 15th, 2025, it was confirmed that the UK's Information Commissioner's Office (ICO) handed out a £14 million fine to Capita. This action comes after a major data breach that took place in 2023.

The data breach at Capita has shaken the industry and shows the ongoing cybersecurity weaknesses at the large UK professional services company.

The Capita data breach happened in March 2023 when hackers broke into Capita's systems, resulting in them stealing almost a terabyte of data and then using ransomware.

The stolen data was wide-ranging. It included staff records, pension details, financial information, and criminal records.

So far, the ICO's investigation shows the attackers got in and took data between March 29th and 30th. The first security breach happened on March 22nd; however, it was indicated that Capita’s delayed response allowed the threat to grow much worse.

What Does This Fine Mean for Corporate Accountability?

This data breach at Capita shows the failure of management and technical controls at a business that handles large amounts of data for the public and private sectors. 

When a large outsourcer like Capita has a major breach, the effects are felt by all its clients. In this case, the breach affected hundreds of pension schemes.

Regulators have warned businesses for years. They warned about the results of ignoring basic cybersecurity practices. The ICO's report details long-term neglect. Capita did not act on known security weaknesses many times. This inaction made the attack possible.

This fine for Capitais is the result of the 325 businesses whose pension schemes were affected. It pushed them into crisis management.

But, this fine due to the Capita data breach is a clear warning that company boards are personally responsible for cybersecurity mistakes.

The Capita data breach weakens the trust that is given to large outsourcing partners. It also shows that following the rules is an ongoing task.

The Regulator's Verdict: The ICO’s Decision on Capita

The Information Commissioner's Office (ICO) is the UK's independent data protection authority. Its main job is to protect information rights. It also applies data protection laws.

This is different from threat actors who are looking for money. The ICO looks into data breaches. It decides if a company did not meet its legal duty to guard personal data.

Capita CEO Adolfo Hernandez joined the company the year after the Capita data breach. In his response, he said he has sped up the company's cybersecurity changes. He also said the business has greatly improved its cybersecurity position.

Issues With the Capita Data Breach Highlighted by the ICO:

  • Poor Security Design: Capita did not set up a tiered admin account system. This issue was noted inside the company at least three times. This simple security step could have stopped the attackers. It would have kept them from getting higher access levels and moving through the network.
  • Very Slow Response: An automated alert was sent within 10 minutes after a bad file was downloaded. But Capita took 58 hours to separate the affected device from the network. This was much longer than their one-hour goal for high-priority alerts. The delay was partly because of too few staff in the Security Operations Center.
  • Ongoing Negligence: Important systems were apparently tested only one time. This was when they were first set up. Additionally, the results of these tests were not passed between different teams. This allowed major risks across the whole company to be ignored. These risks were not lessened for years.

How to Avoid a Similar Compliance Disaster?

The Capita data breach shows that major failures often happen when basic things are ignored. They do not usually come from complex attacks that are impossible to stop. Attackers used known security weaknesses. These weaknesses were not fixed for a long time.

A breach from a vendor or from inside a company can become a disaster. To prevent this, it is necessary to have a proactive security position.

This position should value continuous checking and quick responses. This data breach at Capita shows that having security tools is not enough. It is not enough if alerts and internal warnings are ignored.

No system is completely safe if fundamental security ideas are ignored. Companies must learn from Capita's mistakes.

  • This includes setting up correct network divisions and access controls. A tiered admin system greatly decreases the danger of someone getting higher access levels. This was a main part of this breach.
  • Also, a Security Operations Center (SOC) with enough staff and authority makes sure that important alerts get an immediate response, and not hours or days later. If a threat is stopped in minutes, attackers cannot steal terabytes of data.
