From supply chain risks to sophisticated DDoS attacks, modern cyber threats demand defences that prioritise both protection and rapid recovery. In an exclusive interview with BusinessDay, Oyaje Idoko, Founder and Chief Executive Officer of Layer3 Limited, discusses how Layer3Cloud integrates firewalls, encryption, zero-trust access, and multi-zone infrastructure to protect client assets and guarantee service restoration when it matters most. Excerpts:

How are cybersecurity risks evolving as Nigerian institutions move to multi-cloud environments, and where are the primary vulnerabilities?

As institutions move from legacy systems to multi-cloud environments, their security exposure expands across applications, users, devices and providers. The main vulnerabilities often lie in weak access controls, misconfigured cloud resources, unsecured interfaces and gaps in monitoring. Moving an application to the cloud does not automatically make it secure.

At the network backbone level, unpatched equipment, exposed management systems, inadequate segmentation and dependence on critical links or suppliers remain important concerns. Layer3’s experience across connectivity, enterprise networks and cloud reinforces our view that security must be designed into the entire environment, with clear responsibilities, continuous monitoring and tested recovery arrangements.

How does Layer3 protect sensitive data locally without sacrificing performance or scalability?

Layer3Cloud combines local data residency with infrastructure across availability zones in Lagos and Abuja, enabling customers to design for resilience while benefiting from proximity to Nigerian users. Encryption, firewalls and role-based access controls support data protection, alongside our ISO 27001, ISO 27017 and PCI DSS credentials.

However, sovereignty goes beyond server location. Institutions must understand who can access their data, where backups reside and how information can be recovered or moved. Our approach brings together local infrastructure, scalable capacity and Nigerian-based technical support to help customers meet their security and operational requirements.

How does Layer3 make continuous monitoring, incident response and Zero Trust accessible without substantial capital expenditure?

Building an effective Security Operations Centre requires specialist people, technology and sustained investment. Layer3’s managed security offering brings together threat detection, vulnerability management, SOC monitoring and incident response, reducing the need for customers to build and operate these capabilities independently.

Zero Trust can also be implemented progressively through stronger authentication, least-privilege access, network segmentation and continuous verification. By defining service coverage, escalation procedures and response responsibilities around each customer’s risks, a managed approach makes security investment more focused and manageable.

How is Layer3 protecting its infrastructure against DDoS attacks, zero-day threats and supply chain vulnerabilities?

Our approach is based on layered protection and resilience. Layer3Cloud’s protections include DDoS protection, encryption, firewalls and role-based access, supported by infrastructure across multiple availability zones. These capabilities provide complementary safeguards and options for business continuity.

DDoS resilience requires coordination across the connectivity chain, while zero-day and supply chain risks demand disciplined access management, monitoring, vendor oversight and recovery planning. We do not disclose detailed internal security configurations publicly, but our guiding principle is clear: continuously reduce risk, limit the impact of incidents and maintain the ability to restore services effectively.

What policies and collaborations are needed to build a trusted digital economy and attract investment?

Nigeria needs clear, coordinated requirements across the NCC, NITDA, NDPC and sector regulators. Businesses and investors should understand their obligations concerning data hosting, protection and incident reporting. Localisation policies must also be supported by investment in power, fibre, data centres, cybersecurity talent and affordable long-term financing.

We also need stronger collaboration between infrastructure providers, enterprises, regulators and national incident-response teams through threat-information sharing and joint preparedness exercises. Public procurement should give qualified indigenous providers fair opportunities, while encouraging competition, interoperability and avoiding excessive dependence on any single provider.

Digital sovereignty should strengthen Nigeria’s ability to participate confidently in the global economy. At Layer3, our ambition is to help build the trusted infrastructure that enables businesses to grow, attracts sustained investment and delivers peace of mind.
