Security services
VEXA provides offensive security and security engineering services across web & APIs, cloud-native infrastructure, Kubernetes, and AI/LLM-based features – with clear reporting and remediation support. The goal is to model realistic attackers and give you a prioritised, fixable plan rather than a noisy scanner dump.
Book a security assessment →Offensive testing & red teaming
These services focus on how your systems actually break under attack – from a single web app to multi-cloud environments and AI assistants.
Deep manual testing of web apps, B2B portals, and backend APIs, with focus on authentication, authorisation, data exposure and business logic flaws.
- OWASP Top 10 and advanced logic issues (IDOR, race conditions, workflow abuse).
- Multi-tenant separation checks for B2B and finance-style applications.
- API-specific issues – mass assignment, broken object level authorisation, rate limiting gaps.
- File upload, SSRF, deserialisation and other high-impact vectors where relevant.
- Clear reproduction steps and PoCs so your engineers can retest easily.
Scenario-based offensive exercises that mimic realistic attacker behaviour against people, processes, and technology – with defined rules of engagement.
- Goal-based assessments (e.g., sensitive data access, lateral movement, persistence).
- External, internal or hybrid scenarios depending on your threat model.
- Use of phishing/social engineering where explicitly allowed and scoped.
- Detection & response gap analysis and blue-team feedback.
- Executive-ready reporting for leadership plus detailed technical notes for engineers.
Security testing focused on AI features – including chatbots, copilots, and LLM-based workflows – to identify prompt injection, unsafe tool usage and data leakage paths.
- Prompt injection, jailbreaks and indirect prompt injection (via documents / tools).
- Data exfiltration risks across chat history, knowledge base and integrated systems.
- Abuse of tools, plugins and external connectors (e.g., file access, email, tickets).
- Review of guardrails, content filters and fallbacks.
- Recommendations for safer patterns and monitoring around AI features.
Cloud, Kubernetes & architecture reviews
Cloud and K8s security services focus on misconfigurations, attack paths and architecture-level weaknesses that matter in practice.
A configuration and attack-path review of your AWS/Azure and Kubernetes environments, focusing on how misconfigurations can be chained in practice.
- IAM roles, policies and privilege escalation paths across services.
- Network exposure – security groups, NSGs, firewalls, ingress/egress paths.
- K8s RBAC, Pod Security, hostPath volumes and privileged workloads.
- Cluster add-ons, service accounts and secrets handling.
- Container image, registry & supply-chain checks.
A structured review of your cloud architecture against security best practices and industry guidance, with prioritised hardening steps for your teams.
- Baseline review against cloud security benchmarks (CIS-style controls).
- Data protection – encryption, key management, backups and recovery.
- Logging, monitoring and alerting coverage for key services.
- Secure patterns for multi-account / multi-subscription setups.
- Actionable roadmap you can plug into your engineering backlog.
Typical engagement examples
Every organisation is different, but these examples show how a VEXA engagement can look in practice.
A fast-growing SaaS company wants to validate its security posture before onboarding larger enterprise customers.
- Scope: customer-facing portal, key APIs and the core cloud environment.
- Approach: manual web/API pentest, review of auth & RBAC, multi-tenant checks.
- Cloud review for exposed services, IAM gaps and network misconfigurations.
- Outcome: prioritised report (quick wins + strategic items) and a follow-up call with engineering teams to plan remediation.
A product team has added an AI assistant that can see tickets, documents and internal tools, and wants to understand the risks.
- Scope: AI assistant flows, prompt templates, integrated tools and data sources.
- Approach: targeted prompt injection, data exfiltration attempts, tool abuse tests.
- Review of guardrails, logging and safe patterns around the AI feature.
- Outcome: clear list of abuse scenarios, improved guardrail design and recommendations for monitoring.
How we work with companies
VEXA is designed to be an easy partner for busy teams – from small startups to larger organisations with formal security and compliance programs.
- Scoping call to understand your architecture, timelines and goals.
- Clear proposal with scope, assumptions, testing window and deliverables.
- Testing with periodic check-ins for critical findings.
- Draft report, review call and final report delivery.
- Optional remediation review / retesting.
- Executive summary in business language for leadership.
- Technical details, PoCs and reproduction steps for engineers.
- Prioritised remediation recommendations (quick wins vs long-term).
- Optional mapping of findings to common controls (e.g., ISO/SOC2-style).
- Support over email/meetings as teams implement fixes.
