Full-Spectrum Cybersecurity
From VAPT and red team simulations to smart contract audits, cloud security assessments, incident response, and post-quantum cryptographic resilience — Xenqube delivers security across every layer of your stack. Not a checkbox. A continuous posture.
Coverage
What We Secure
Security at Xenqube is not isolated to one domain. We cover infrastructure, applications, smart contracts, AI systems, and cryptographic layers — with a unified threat model.
Cybersecurity
Applications & Infrastructure
Web apps, APIs, mobile apps, internal networks — assessed for real-world exploitability with actionable remediation.
VAPT Services →Web3
Smart Contract & Protocol
Reentrancy, access control, oracle manipulation, flash loan attacks, and upgrade risks — caught before audit, not after.
Web3 Security →AI
Adversarial AI & Agent Security
Prompt injection, data poisoning, model inversion, and supply-chain attack mitigations for AI agents in production environments.
AI Security →PQC
Post-Quantum Cryptography
Quantum threat assessment, NIST PQC migration planning, and hybrid classical/PQC deployment for long-lived systems.
PQC Migration →VAPT
Vulnerability Assessment & Penetration Testing
We identify real exploitable vulnerabilities — not just scan output. Every assessment combines automated tooling with manual testing by experienced security engineers, and delivers a prioritized remediation roadmap with evidence.
API Security Testing
REST and GraphQL endpoint enumeration, broken object-level authorization (BOLA/IDOR), mass assignment, rate-limiting gaps, and token security testing for production APIs.
Request Assessment →Mobile App VAPT
Android and iOS security testing covering data-at-rest, insecure communications, improper platform usage, reverse engineering risk, and certificate pinning bypass analysis.
Request Assessment →Network & Infrastructure Pentest
Internal and external network scanning, open port and service enumeration, misconfiguration analysis, firewall rule assessment, and privilege escalation path mapping.
Request Assessment →Cloud Security Assessment
AWS, GCP, and Azure posture review covering IAM misconfiguration, overly permissive policies, exposed storage buckets, secrets management, and network segmentation gaps.
Request Assessment →Secure Code Review
Manual static analysis covering injection vulnerabilities, cryptographic misuse, insecure deserialization, hardcoded secrets, and architectural security flaws in source code.
Request Review →Advanced Testing
Red Team & Adversarial Simulation
Red team engagements go beyond scope-limited VAPT. We simulate real-world attackers — combining social engineering, physical access probing, and multi-stage exploitation chains — to test your detection and response capability, not just your patch status.
Full Red Team Engagement
Goal-based adversary simulation with no fixed scope. Objective: demonstrate attacker capability to reach critical assets — keys, admin access, sensitive data, or fund movement — before you do.
Start Engagement →Phishing & Social Engineering
Spear phishing campaigns, pretexting, and vishing simulations against your team to measure susceptibility and strengthen human-layer defenses before real attackers do.
Run Simulation →Purple Team Exercise
Collaborative red-blue team sessions where offensive findings are mapped directly to detection gaps — improving SIEM rules, alert tuning, and incident response runbooks in real time.
Book Exercise →Response
Incident Response & Digital Forensics
When something goes wrong — a breach, a ransomware hit, a compromised key, or an unexplained transaction — response speed and forensic quality determine outcome. Xenqube provides both reactive IR support and proactive IR readiness programs.
Breach Investigation & Containment
Rapid triage, scope determination, containment actions, and evidence preservation for active incidents — including smart contract exploits, wallet compromise, and infrastructure breaches.
Emergency Contact →Digital Forensics
On-chain transaction tracing, log analysis, memory forensics, and root-cause reconstruction for post-incident reporting, regulatory disclosure, and legal proceedings.
Request Forensics →IR Readiness & Playbook Design
Severity matrix design, runbook authoring for your most likely threat scenarios, tabletop exercise facilitation, and detection engineering to shorten time-to-response before an incident occurs.
Build Your Playbook →Web3 & Smart Contracts
Smart Contract & Protocol Security
Security review is embedded from architecture through deployment — with audit-ready artifacts produced at each milestone. We do not just check for reentrancy. We model your protocol's entire attack surface.
Security Audit Preparation
Pre-audit review covering natspec documentation, test coverage, access control mapping, and threat model artifacts so third-party audits are faster and more thorough.
Smart Contract Checklist →Web3 Security Operations
Ongoing security operations: threat modeling, monitoring, wallet governance, key rotation procedures, and incident response for live protocols.
Security Operations →Enterprise Web3 Security
Enterprise-grade security programs: controls mapping, evidence collection, compliance alignment, and security reporting for institutional and regulated deployments.
Enterprise Security →Training
Security Workshops & Awareness
Technical controls are only as strong as the people operating them. Xenqube delivers hands-on security workshops — from secure coding practices to Web3 threat modeling — tailored to your team's stack and role profile.
Secure Development Workshop
Hands-on training covering OWASP Top 10 exploitation and defense, secure coding patterns, secrets management, dependency risk, and threat modeling for engineering teams.
Book Workshop →Web3 Security Workshop
Smart contract attack patterns, DeFi protocol risks, wallet security, key management hygiene, and on-chain monitoring fundamentals — practical sessions for protocol teams.
Book Workshop →Security Awareness & Governance
Executive and leadership-level sessions covering threat landscape, security program framing, incident communication, regulatory obligations, and board-ready security metrics.
Request Session →Post-Quantum Cryptography
Cryptographic Resilience
Classical cryptography underpins most infrastructure today — and it is vulnerable to future quantum computers. Xenqube helps organizations understand their exposure and migrate to NIST-standardized PQC algorithms before the window closes.
Assessment
Quantum Threat Assessment
Inventory of classical cryptography in your stack, risk rating against quantum timeline scenarios, and migration priority scoring.
Migration
Hybrid PQC Deployment
Phased migration using hybrid classical + PQC schemes — maintaining compatibility with existing systems while building quantum resistance.
Algorithms
PQC Algorithm Selection
Guidance on ML-KEM, ML-DSA, SLH-DSA, and FN-DSA selection based on your performance, compatibility, and assurance requirements.
