In today’s hyperconnected world, cyber threats evolve faster than ever. From advanced phishing and ransomware to cloud misconfigurations and API abuse, attackers continuously target digital infrastructures to exploit weak links. For global enterprises expanding across Southeast Asia particularly in Vietnam maintaining a robust security posture is not optional, it’s essential.

Cyberintelsys, a CREST accredited cybersecurity provider, empowers organizations to proactively identify, mitigate, and prevent vulnerabilities through globally recognized Vulnerability Assessment and Penetration Testing (VAPT) services. Backed by certified professionals and proven methodologies, Cyberintelsys helps businesses build lasting cyber resilience and earn the trust of their customers, partners, and regulators.

Why CREST Accreditation Matters

When it comes to cybersecurity assurance, credibility and consistency matter most. The Council of Registered Ethical Security Testers (CREST) is an internationally recognized accreditation body that certifies service providers for their technical excellence, ethical standards, and structured testing methodologies.

Cyberintelsys’s CREST-accredited VAPT services demonstrate compliance with globally accepted best practices, providing assurance that every test is:

• Conducted by qualified professionals under strict ethical standards

• Based on repeatable, auditable methodologies aligned with CREST, OWASP, NIST, OSSTMM and PTES

• Delivered through controlled and authorized engagements to ensure zero operational disruption

• Supported by rigorous quality assurance and verified technical reports

For clients across Vietnam and beyond, CREST accreditation means every engagement delivers verified results, transparent processes and credible security assurance.

Comprehensive VAPT Services Offered by Cyberintelsys

Cyberintelsys provides end-to-end VAPT services that cover every layer of your digital ecosystem—from web and mobile to cloud and infrastructure environments. Each engagement is carefully scoped and executed by certified experts who simulate real-world attack scenarios while maintaining full compliance with client policies.

1. Web Application Penetration Testing

Web applications are the lifeblood of modern digital businesses but are also a frequent target for exploitation.
Cyberintelsys conducts in-depth testing to identify OWASP Top 10 vulnerabilities such as SQL injection, XSS, insecure deserialization, authentication flaws, and access control issues. Our team uses both automated tools and manual analysis to uncover complex business logic vulnerabilities that scanners often miss.

2. API Penetration Testing

With APIs driving integrations and data exchange, securing them is critical. Cyberintelsys’s API testing approach evaluates authorization flows, rate limiting, token handling, and data exposure to ensure APIs are protected against abuse. This service helps safeguard critical communication channels and prevents data leakage across your connected systems.

3. Mobile Application Security Testing

In Vietnam’s mobile-first market, ensuring the security of iOS and Android apps is vital. Cyberintelsys tests applications for insecure data storage, weak encryption, API misconfigurations, and reverse engineering vulnerabilities. Our comprehensive testing ensures that mobile applications meet compliance, protect user data, and remain resilient against evolving threats.

4. Network Penetration Testing

A single misconfiguration in your internal or external network can open the door to attackers. Cyberintelsys evaluates network segmentation, firewall policies, endpoint protection, and access controls to identify exploitable weaknesses. By simulating attacker behavior, our specialists provide actionable insights to strengthen your overall network defense.

5. Infrastructure Security Assessment

Beyond applications and endpoints, your infrastructure forms the foundation of digital operations. Cyberintelsys performs server configuration reviews, router hardening, patch validation, and privilege escalation testing to ensure your IT assets meet the highest security standards. This helps prevent lateral movement and data compromise within enterprise systems.

6. Cloud Security Assessment

As more Vietnamese and global organizations adopt AWS, Azure, and Google Cloud, cloud misconfigurations have become one of the most exploited attack vectors. Cyberintelsys reviews IAM policies, S3 buckets, key management, and logging configurations to help clients maintain secure and compliant cloud environments.

7. Red Teaming & Adversary Simulation

For organizations that want to test their true cyber resilience, Cyberintelsys conducts Red Team engagements that simulate advanced persistent threats (APTs) and real-world attacker tactics.
These assessments measure:

• Security detection and response capabilities

• Incident handling and containment effectiveness

• Employee awareness and social engineering resistance

This real-world testing helps organizations strengthen not just their defenses, but also their response strategy and cyber maturity.

Cyberintelsys Proven CREST-Aligned Methodology

Each assessment follows a globally recognized and CREST-aligned methodology that ensures thoroughness, transparency, and repeatability across engagements.

1. Scoping & Planning

Cyberintelsys begins by understanding your business environment, defining testing objectives, and determining in-scope assets. Engagement rules are set clearly to ensure compliance and operational safety.

2. Reconnaissance & Mapping

Our experts gather intelligence on applications, networks, and systems to understand potential entry points. Both passive and active reconnaissance techniques are used to build a complete attack surface view.

3. Vulnerability Identification

Automated tools and manual verification processes are used to detect and validate potential weaknesses. This phase ensures that false positives are minimized and only verified issues are reported.

4. Exploitation & Validation

Ethical hackers simulate controlled attacks to assess the real-world impact of discovered vulnerabilities. The goal is to demonstrate potential damage without disrupting live operations.

5. Post-Exploitation & Lateral Movement

Once access is achieved, Cyberintelsys evaluates privilege escalation paths, lateral movement potential, and data exfiltration risks to measure the depth of possible compromise.

6. Reporting & Remediation Guidance

Clients receive both executive summaries and detailed technical reports. Each finding is prioritized based on business risk, along with step-by-step remediation recommendations.

7. Retesting & Continuous Validation

After remediation, Cyberintelsys performs retesting to verify that all vulnerabilities have been successfully mitigated. This ensures lasting security assurance and compliance readiness.
