The South African Information Regulator has shifted to proactive enforcement of POPIA compliance, demanding proof of data protection from companies. This move follows a massive surge in security notifications, which rose from 202 in 2021/2022 to 2,898 in 2025/2026.
Why it matters
Large organisations are increasingly holding SME suppliers accountable as attackers exploit these connections to bypass security. This trend has made third-party and supply chain risk the leading resilience challenge for 65% of large local organisations.
Security notifications reached 2,898 in 2025/2026, including over 1,200 in the first half of 2026 alone. Third-party involvement now accounts for 48% of all breaches, marking a 60% year-on-year increase in such incidents.
The players
Information Regulator
This is the independent body established to oversee the protection of personal information and access to information in South Africa.
Satrix
This is a prominent South African provider of index-tracking investment products.
Bidvest Bank
This is a South African bank that provides specialised financial services to individuals and businesses.
EasyEquities
This is a digital investment platform that allows users to purchase fractional shares in local and international markets.
The details
The regulator is sending direct letters to firms to verify their POPIA compliance, specifically targeting vulnerabilities within software vendors and service providers. High-profile entities including Satrix, Bidvest Bank, and EasyEquities have previously suffered data exposures tied to these third-party links.
Timeline
Security notifications totalled 202 during the 2021/2022 period.
Reported security compromises rose to 2,898 in 2025/2026.
More than 1,200 security notifications were submitted in the first half of 2026.
Supply chain attacks emerged as a primary cyber-threat theme throughout 2026.
The Tech Race
This regulatory shift reflects a transition from voluntary data stewardship to enforced supply chain resilience within the South African corporate sector. It signals the end of a legacy approach where enterprises could isolate their internal networks from third-party vendor weaknesses.
Customers can expect more rigorous data verification requests when interacting with service providers as businesses tighten their security protocols. These measures aim to reduce the frequency of data leaks that often compromise personal financial and identity records held by third-party platforms.
The takeaway
Businesses must now audit their entire vendor ecosystem to ensure alignment with POPIA requirements rather than relying on internal firewalls alone. Implementing robust third-party risk management is the most effective way for local organisations to mitigate the rising threat of supply chain exploitation.
