AI critical in global cybersecurity war - PwC



Wednesday, October 15, 2025 The study also found key weak points around authentication controls (55 per cent), connected devices (48 per cent), legacy systems (45 per cent) and supply chain vulnerabilities (43 per cent), areas that attackers continue to exploit.

Consulting and Risk Services Leader at PwC Nigeria, Femi Osinubi, said Nigerian organizations must take cybersecurity more seriously as digital transformation deepens across sectors.“As organizations in Nigeria advance on their digital transformation journey, the need for resilient cybersecurity strategies has never been more critical,” Osinubi said. “AI offers a powerful opportunity to strengthen defences, but success depends on bridging the skills gap and integrating these tools into broader risk frameworks.”

He added that Nigerian businesses should invest in AI-driven cyber tools while upskilling local talent, noting that “combining technology and human capability is key to protecting Nigeria’s digital economy and infrastructure.”

According to PwC, nearly eight in ten organizations (78 per cent) globally plan to increase their cybersecurity budgets in the next 12 months. Among their top priorities, AI investment leads with 36 per cent, ahead of cloud security (34 per cent), network security (28 per cent) and data protection (26 per cent).

However, spending more money does not necessarily translate to stronger defences. About half (50 per cent) of respondents cited a lack of knowledge in applying AI for cyber defence, while 41 per cent pointed to the scarcity of skilled professionals as a major challenge.

Global Cybersecurity and Privacy Leader at PwC US, Sean Joyce, described the current landscape as a “tipping point,” driven by rapid digital interconnectivity and emerging threats. “The most successful organizations are those where chief information security officers (CISOs) have a seat at the table and cybersecurity is embedded in business decisions,” Joyce said. “Resilience comes from foresight, not hindsight.”
