Cybersecurity & Threat Defense

Proactive vulnerability assessments, elite penetration testing, Zero Trust architecture, and incident response readiness designed to defend mission-critical systems against sophisticated cyber attacks.

Executive Briefing

Defending the Modern Enterprise in an Evolving Threat Climate

In an era where ransomware-as-a-service, targeted phishing, and credential-stuffing campaigns exploit the weakest links across corporate networks, passive defenses are no longer sufficient.

ACE ICT Consult helps Nigerian commercial banks, fintechs, government parastatals, and private enterprises build resilient, battle-tested cyber defenses. We move beyond cosmetic compliance, delivering offensive penetration testing, defensive architecture engineering, and continuous governance that protects revenue, client trust, and intellectual capital.

Core Capabilities

Comprehensive Cybersecurity Practice Areas

Our multidisciplinary security services provide 360-degree visibility and protection across networks, cloud workloads, applications, and the human workforce.

Pillar 01

Vulnerability Assessment & Penetration Testing (VAPT)

Offensive security testing simulating real-world adversary tactics, techniques, and procedures (TTPs):

Web Application Penetration Testing: In-depth testing covering the OWASP Top 10, including Broken Object Level Authorization (BOLA), SQL Injection, SSRF, and business logic flaws.
External & Internal Network VAPT: External attack surface mapping, perimeter firewall audits, internal network pivoting, and Active Directory exploitation simulation.
API & Mobile App Security: Testing iOS and Android mobile binaries, reverse engineering defenses, and REST/GraphQL API gateway authentication.
Executive & Technical Reporting: Clear CVSS v3.1 severity scores, proof-of-concept exploits, and step-by-step developer remediation guidance.

Pillar 02

Zero Trust Architecture & Identity Governance

Enforcing the principle of "Never Trust, Always Verify" across every digital transaction and endpoint:

Identity & Access Management (IAM): Context-aware authentication, mandatory Multi-Factor Authentication (MFA), and automated employee provisioning/deprovisioning.
Privileged Access Management (PAM): Vaulting administrative credentials, eliminating shared passwords, session recording, and implementing just-in-time (JIT) access elevation.
Micro-Segmentation: Isolating database servers, payment processing clusters, and domain controllers behind software-defined boundaries to halt lateral movement.
Endpoint Protection (EDR / XDR): Real-time endpoint telemetry, behavioural anomaly tracking, automated process isolation, and USB device control.

Pillar 03

Incident Response & Ransomware Readiness

Minimizing business downtime and data loss when a critical security event or breach occurs:

Incident Response Playbooks: Documented, step-by-step procedures covering containment, eradication, and forensic recovery following SANS/NIST standards.
Ransomware Simulation Drills: Testing network segmentation, immutable backup isolation, and emergency communications under simulated crisis conditions.
Digital Forensics & Root Cause Analysis: Preserving digital chain-of-custody, analyzing memory dumps and event logs to trace entry vectors.
Statutory Breach Notification: Guiding executive leadership in meeting NDPA 2023 72-hour regulatory breach disclosure mandates to the NDPC.

Pillar 04

Human Firewall & Security Culture

Transforming employees from the primary vulnerability into the first line of enterprise defense:

Contextual Phishing Simulations: Automated phishing campaigns mimicking realistic local scenarios (e.g. banking alerts, tax invoices, executive spear phishing).
Interactive Awareness Academies: Engaging micro-modules covering clean desk policies, safe remote work, social engineering, and password hygiene.
Executive & Board Cyber Briefings: Strategic sessions for C-suite leaders and Non-Executive Directors addressing fiduciary duties, legal liability, and cyber insurance.
Secure Coding Training: Equipping internal development teams to write clean code immune to injection and cross-site scripting vulnerabilities.

Structured Methodology

From Vulnerability to Verified Defense

Reconnaissance & Discovery

We map your external digital footprint, catalog public IPs, exposed ports, cloud assets, and leaked credentials.

Vulnerability Analysis & Exploitation

We combine automated scanning with deep manual exploitation to identify high-impact, real-world breach paths.

Remediation Engineering

We assist your engineering teams in patching vulnerabilities, reconfiguring access rules, and hardening architectures.

Verification & Attestation

We perform rigorous re-testing to certify that vulnerabilities have been effectively resolved, issuing official VAPT clearance reports.

Technical Insight

Understanding Modern Ransomware: How Adversaries Traverse Corporate Networks

Ransomware attacks are rarely instantaneous. Modern threat actors spend an average of 9 to 16 days moving through corporate networks before executing payloads. Understanding the attack chain is key to breaking it early:

Phase 1: Initial Infiltration via Credential Theft or Unpatched VPNs

Adversaries routinely gain access via stolen employee credentials obtained from infostealer malware or by exploiting unpatched edge devices (such as remote access gateways and SSL-VPN appliances). Weak passwords and the absence of MFA on remote portals remain the primary ingress point.

Phase 2: Internal Reconnaissance & Privilege Escalation

Once inside a single workstation, attackers do not immediately encrypt files. Instead, they run tools like BloodHound and Mimikatz to dump memory, harvest cached credentials, and map paths to Active Directory Domain Admins.

Phase 3: Lateral Movement & Backup Neutralization

Attackers pivot from workstation to workstation using legitimate administrative protocols like RDP, WMI, and PowerShell. Crucially, they seek out backup servers, cloud consoles, and virtual machine snapshots to delete or encrypt them first, ensuring the victim cannot recover without paying.

Phase 4: Double Extortion & Enterprise Encryption

Sensitive intellectual property, customer financial records, and employee data are exfiltrated to offshore command-and-control servers. Only after data theft is complete do attackers push ransomware payloads via Group Policy (GPO) to all connected servers and endpoints simultaneously.

Frequently Asked Questions

Will penetration testing disrupt our live production systems or services?

No. ACE ICT Consult follows rigorous Rules of Engagement (RoE). Offensive tests are scheduled during designated maintenance windows or business hours with carefully throttled payloads. Our ethical hackers maintain constant communication with your technical leads throughout the assessment.

How often should an enterprise perform VAPT?

Industry standards (such as PCI-DSS and CBN guidelines) mandate at least annual comprehensive penetration testing, as well as testing following any major software release, network architectural modification, or merger. Many leading institutions perform quarterly automated vulnerability scanning paired with biannual penetration testing.

What documentation is provided after a security assessment?

We provide two key deliverables: (1) An Executive Summary with risk matrices for the Board and Executive Management, and (2) A Technical Remediation Manual detailing exact replication steps, code-level snippets, and patch references for internal sysadmins and developers.
