Africa’s critical infrastructure operators and digital platforms are confronting a rapidly compressing cyber defence window. According to the esentry 2025 Annual Threat Report, titled “The Evolved Phalanx,” determined threat actors can now progress from initial compromise to operational positioning within five days, fundamentally altering how organisations must think about resilience.

Released by esentry, one of Africa’s leading indigenous Managed Security Service Providers, the report is based on extensive operational telemetry collected throughout 2025. During the year under review, esentry’s security operations processed more than 31 billion discrete security events, escalated 3.5 million actionable alerts, and neutralised over 15,000 confirmed malicious attempts. The scale of monitoring provides rare visibility into the velocity and evolution of modern attacks across the continent.

While financial institutions remain a primary target, the threat landscape has expanded rapidly to include digital lending platforms, healthcare networks, and telecommunications operators. These sectors, deeply embedded in everyday economic and social systems, present high-impact opportunities for adversaries seeking disruption, extortion, or strategic leverage.

A defining shift identified in the report is the move away from overt system exploitation toward the abuse of legitimate access. Increasingly, attackers are leveraging compromised credentials and so-called “living-off-the-land” techniques to blend into normal enterprise activity and delay detection. By the fifth day of an intrusion, esentry’s data indicates that many actors have already mapped internal networks, identified high-value systems, and profiled user behaviour sufficiently to plan lateral movement.

“What we are witnessing is a structural acceleration in threat velocity,” said Gbolabo Awelewa, Chief Business Officer at esentry. “Five days is now sufficient for a determined actor to understand an environment. Organisations not engineered for rapid detection and containment are operating with a dangerous blind spot, as the journey from entry to operational disruption now unfolds at unprecedented speed.”

In response to this compression, esentry has transitioned its operations into what it describes as a unified “Phalanx” formation, integrating intelligence and engineering to coordinate a defensive posture. According to the company, this model enables the containment of low-complexity incidents in under 90 seconds by combining structured threat hunting with centralised telemetry and disciplined response protocols.

The report also highlights sector-specific exposures. In healthcare, ransomware remains a significant threat, particularly when Remote Desktop Protocol configurations are left exposed. Within financial services and telecommunications, the surge in credential abuse and info-stealer malware reflects the exploitation of trusted digital relationships that underpin interconnected ecosystems. As Africa accelerates its digital transformation, these expanding attack surfaces demand architectural resilience rather than incremental security upgrades.

For boards and executive leadership teams across West Africa, the report reframes cyber governance as a matter of speed and coordination. Resilience, it argues, will no longer be defined by the number of security products deployed, but by measurable detection velocity and containment capability. In an environment where five days may determine whether an intrusion becomes a crisis, preparedness has shifted from a technical function to a strategic imperative.
