Penetration Testing
Test web applications, APIs and internal or external networks for exploitable weaknesses. Investigate authentication, access controls, business logic and attack paths within an agreed scope.
Web2 Security
Security assessments for applications, cloud and AI
Find weaknesses in the software and infrastructure your business relies on. CD Security assesses web applications, APIs, networks, cloud environments and AI-powered workflows, with a scope built around your systems and priorities.

Start with the systems that matter most
A new product launch, an enterprise customer review or a major infrastructure change can raise different security questions. We help you define the assessment that answers yours.
Our work covers exploitable application weaknesses, infrastructure exposure, cloud permissions and the additional risks introduced by AI integrations. You can assess one part of your environment or agree a coordinated review across connected systems.

Explore Penetration Testing
Cloud & Infrastructure Security
Review AWS, Azure or GCP environments for exposed resources, misconfigurations, excessive permissions and infrastructure weaknesses that could put your systems and data at risk.
AI & LLM Application Security
Assess how your application handles prompts, retrieved content, sensitive data and connected tools. Test whether an attacker can redirect an AI workflow or bypass its permission boundaries.
Security Posture Assessments
Build a clearer picture of your technical exposure. Identify visible assets and security weaknesses, then prioritize improvements in a practical remediation roadmap.

Make security decisions with evidence
A feature can work as intended for ordinary users while exposing data to the wrong account. An infrastructure change can make a private service reachable. A new AI tool can give an untrusted input a route to a privileged action.
An independent assessment helps your team understand these weaknesses before a launch, deployment or customer security review. It gives engineering a defined set of issues to investigate and fix, and gives decision-makers a clearer view of the remaining risk.
A scope your team understands
Define the objective
Tell us what you are building, what has changed and which decisions the assessment needs to support. We agree the assets, access, testing depth and boundaries before work begins.
Assess the relevant risks
We examine the agreed systems using the techniques appropriate to the engagement: application or network testing, source review where included, configuration review or AI workflow testing.
Explain the findings
We document the evidence, likely impact and remediation recommendations. The report distinguishes confirmed weaknesses from areas that need further investigation.
Why CD Security
OSCP-certified researchers with 10+ years of Web2 security experience
Our Web2 team brings more than a decade of offensive security experience across penetration testing, red teaming, exploit development and fuzzing. Our researchers hold OSCP, earned through a demanding practical exam involving nearly 24 hours of hands-on testing, followed by a detailed technical report. Candidates must demonstrate that they can exploit vulnerabilities, escalate privileges and document their findings.
Expert-led testing, reinforced by AI-assisted analysis
Our researchers lead every assessment, investigating your application’s logic, access controls and potential attack paths. AI-assisted analysis adds a second layer of review to help surface overlooked weaknesses and challenge assumptions. Our researchers validate findings and assess their real-world impact before reporting them.
Clear guidance to fix vulnerabilities
You receive findings with supporting evidence, reproduction steps and an explanation of the potential business impact. We prioritize the issues and provide specific remediation guidance so your engineers understand what needs to change, why it matters and what to fix first.
What your team receives
- A summary of the assessed scope, access and important limitations.
- Findings with supporting evidence and an explanation of potential impact.
- Prioritized remediation recommendations for the relevant systems.
- A clear distinction between tested areas and work outside the engagement.
The assessment proposal defines the deliverables and any follow-up work. Fix verification or further testing is agreed separately where required.
Tell us what needs assessing
Share the application, infrastructure or AI workflow you want reviewed, the reason for the assessment and your target timeframe. We will help you identify a suitable scope.
Frequently asked questions
Do we need to be a Web3 company?
No. These services are for software businesses, SaaS teams and organizations operating applications, infrastructure or AI-powered workflows. You do not need a blockchain product to work with us.
Which assessment should we choose?
Choose penetration testing for a defined application, API or network you want tested for exploitable weaknesses. Choose a cloud review for configuration and permissions, or AI security testing for risks in an AI workflow. If you need a broader technical picture before deciding what to test in depth, start with a posture assessment.
Can one engagement cover multiple areas?
Yes, where that is useful and agreed in scope. An application and its cloud permissions may need to be reviewed together, for example. We define the assets and depth of each assessment rather than assuming every service is included.
How are cost and timing determined?
They depend on the systems involved, their complexity, the number of security researchers assigned and the urgency of the review. Share your requirements and target dates so we can define an appropriate scope and quote.
Can an assessment support a customer security review?
It can provide technical findings and evidence of the work performed. Share any customer requirements before scoping so the assessment can be designed around them. Acceptance depends on the reviewing party’s requirements.
