Our application security services

Application security assessment

We provide the full scope of application security (AppSec) assessments to confirm the proper protection and cyber threat resilience of your web and mobile applications.

Our team thoroughly evaluates the application’s architecture, identifies design-level security issues, and recommends improvements to ensure secure data flows across all components and external integrations.

Our experts conduct in-depth source code review to detect hidden issues and risks like insecure cryptographic algorithms implementation or exposed credentials or secrets.

We also perform software composition analysis (SCA) to uncover security vulnerabilities, licensing issues, and software supply chain exposure in software components, including open-source libraries, third-party plugins, and their dependencies.

Application security posture management

We help organizations establish a proactive security risk management strategy to prevent and mitigate security threats and maintain a strong application security posture. As part of the strategy’s implementation, we continuously monitor and assess applications using automated tools to identify weak areas, plan and implement proper remediation strategies, and track the effectiveness of the measures taken over time.

Secure SDLC & DevSecOps enablement

We help companies incorporate security practices into their software development lifecycles (SDLC) to achieve a better security posture of applications. Our team reviews existing development processes and helps teams to implement secure design, coding, deployment and delivery practices that address detected security gaps and weaknesses.

We also help integrate security testing automation, threat modeling, and vulnerability management procedures into DevOps pipelines to identify and prevent security issues at every stage of the development lifecycle.

Our team assists businesses with securing their IT infrastructures by identifying misconfigurations in networks, servers, and data storages, stress-testing infrastructure, and preparing disaster recovery plans to quickly restore operations of IT systems after disruptions.

Our engineers also help ensure cloud security for dynamic, scalable cloud environments by setting up Infrastructure-as-Code (IaC) practices that enforce consistent, secure, and auditable configurations and policies across all cloud resources, with full visibility and control.

App security training

We carry out training sessions to help businesses equip their security teams with the knowledge and practical skills needed to identify, assess, and timely mitigate application risks with confidence, and expertise needed to prevent the negative impact of security threats on critical business processes.

Our application security testing expertise

We offer the full spectrum of application security testing services, combining automated vulnerability scans with manual expert validation to detect both typical vulnerabilities and complex issues, providing in-depth insights into software security levels and risk exposure. We also thoroughly document our test results, describing the nature of existing security loopholes and providing step-by-step remediation guidance over the most effective measures.

Static Application Security Testing

We analyze the app’s source code to identify its vulnerabilities, code errors, and improperly operating security controls, as well as detect potential security risks.

  • Breaking down the code’s structure
  • Detecting insecure coding patterns
  • Analyzing data flows and code execution paths
  • Matching the findings against vulnerability databases like OWASP Top 10, CWE, etc.
  • Prioritizing the findings based on risk level and severity and eliminating false positive results

Dynamic Application Security Testing

We simulate common attacks on running web and mobile apps without accessing their source code to check solutions’ behavior under attack conditions and detect exploitable weaknesses.

  • Collecting details about the running application to locate application-layer attack points
  • Simulating external attacks, including SQL injection, cross-site scripting (XSS), command injection, and API exploits
  • Analyzing the findings and estimating the risks of the revealed vulnerabilities

Interactive Application Security Testing

We run interactive tests to monitor the behavior of the entire application from within at runtime and check how its protection mechanisms respond to attack scenarios in real-time.

  • Embedding dedicated sensor modules into the app
  • Running the app under normal conditions and simulating security attacks
  • Tracking app behavior, including data flows, execution paths, and interactions between app components
  • Detecting, identifying, and prioritizing runtime vulnerabilities

Penetration testing

Our AppSec experts simulate complex, chained mock cyberattacks to explore possible attack paths, assess the exploitability of application vulnerabilities, and evaluate the potential impact of security issues on applications and business processes.

  • Collecting information about the test target using various techniques (e.g., network scanning and threat intelligence)
  • Mapping the attack surface and potential entry points
  • Scanning the application for vulnerabilities and attempting to exploit them
  • Evaluating the impact and risks of successful exploits
  • Retesting after remediation actions have been taken (if needed)

Pre-certification testing

We perform pre-certification testing to help companies evaluate their readiness for security audits and compliance certifications and align their software systems with the required security standards.

  • Define security requirements and testing scope
  • Executing outlined tests and performing code reviews
  • Validating testing results against the standards and identifying compliance gaps
  • Documenting findings using severity ratings
  • Retesting the implemented changes to confirm the software’s updated compliance

Our cooperation options for application security projects

Comprehensive app security services

We handle app security posture management end-to-end, including continuous monitoring, detecting app vulnerabilities, and timely applying of security patches and other measures to ensure fast response to emerging threats and minimize potential operational and business risks for companies.

On-demand app security support

We help organizations address targeted AppSec tasks required for specific projects, app releases, or cases of urgent security threats, offering flexible security support on demand.

FAQs

The number of cyberattacks is constantly on the rise, which underscores the critical need for robust, all-encompassing protection, from secure software design to code security and runtime defenses, to ensure applications can withstand all types of threats.

Moreover, data breaches cost on average as much as $4.4m according to IBM’s research, which urges organizations and their Chief Information Security Officers (CISOs) to establish a comprehensive application security program (AppSec program) and implement comprehensive software security measures that help prevent potential exposure of sensitive corporate and customer data. Writing secure code, implementing secure application development practices, and regularly checking mobile and web applications for vulnerabilities allows cybersecurity risks to be reduced and minimizes the potential damage and disruption they can cause to the business.

Organizations typically use a combination of automated and manual testing tools to identify security weaknesses in their applications. There are dedicated tools for each type of testing, like OWASP ZAP for dynamic testing or Checkmarx for interactive testing. In addition, security teams are increasingly adopting AI-powered security platforms like Snyk or Mend.io that cover multiple AST types and use cases and offer advanced capabilities like AI-driven prioritization, misconfiguration detection, and LLM-powered context‑aware risk scoring, helping security professionals accelerate secure development and reduce manual effort. However, companies should be aware that these advanced features are often available on higher-tier pricing plans. Organizations often complement these tools with managed services to ensure continuous monitoring, timely remediation, and expert handling of security findings.
