When You Need AppSec as a Service
Scaling security without overloading your team
Growing applications need stronger security, but expanding efforts can strain your team. TechMagic provides expert security support without adding to your workload. We support your team, offering tools and expertise to scale security efficiently.
Optimizing and securing legacy applications
Legacy apps often lack modern security, making them vulnerable. We identify and fix weak points like outdated encryption, insecure APIs, and poor access control. Our team strengthens security without requiring a full rebuild.
Seamless DevSecOps integration
Embedding security into DevOps can slow things down, but TechMagic's AppSec service avoids that. We ensure smooth DevSecOps implementation. For this, we automate security testing and apply secure coding from the start so developers get clear guidance and faster feedback. This reduces vulnerabilities without disrupting workflows or delaying releases.
Mitigating cyber threats for business continuity
Cyber threats get more sophisticated every day. Businesses must stay aware to prevent disruptions. Ransomware, denial-of-service attacks, and data breaches threaten applications. Our AppSec as a service ensures a proactive defense as it identifies and fixes vulnerabilities before exploitation.
Protecting sensitive data
Data is a critical asset. Protecting customer records, financial details, and intellectual property is essential. Our app security service protects data with encryption, access control, and safe transmission. We prevent unauthorized access and ensure data remains secure at rest and in transit.
Secure app launch
Security should be built into development, not added later. Our service integrates secure coding, threat modeling, and security tests from the start. This ensures applications are protected from launch and reduces the need for costly fixes.
Our Application Security Testing Services
Implementation guidance for security best practices
Even the most secure application can be compromised if an organization does not follow best practices during implementation. Our implementation guidance service provides your team with detailed instructions on how to integrate security best practices into the development process. This includes guidance on secure authentication, authorization mechanisms, secure data storage, encryption, and secure communication protocols. We communicate transparently with your development team to ensure that security measures are applied consistently throughout the application’s implementation.
Application architecture review
The application security depends a lot on its architecture. During our application architecture review, we assess the design and structure of your application to identify potential security gaps early in the development process. Our team examines factors such as data flow, access control, encryption mechanisms, and integration with third-party systems.
SDLC gap analysis using OWASP SAMM
In the software development lifecycle (SDLC), security practices can often be overlooked or inadequately implemented. Our SDLC gap analysis using OWASP SAMM (Software Assurance Maturity Model) assesses the current state of your development processes and identifies areas where security can be improved. SAMM is a well-established framework for assessing security maturity in the SDLC. Through this analysis, our team provides actionable insights to strengthen your development lifecycle and ensure that security is fully integrated at every stage.
Application threat modeling
Threat modeling is an essential practice in identifying potential security risks early in application development. We detect threats, vulnerabilities, and attack vectors that could be exploited. In the process, we keep transparent communication to understand your application’s features and workflows, assess its attack surface, and develop mitigation strategies to prevent attacks. Our security team uses AWS Threat Composer and OWASP Threat Dragon to map potential risks and provide detailed recommendations on improving security at the architecture level. This helps ensure that security is built into the design and architecture of your application from the outset.
Application security testing
We perform thorough app security testing as a service of your web and mobile applications using a mix of manual and automated methods. This includes static application security testing (SAST), dynamic application security testing (DAST), and software composition analysis (SCA) tools implementation to identify vulnerabilities like insecure data storage, broken access control, or weak authentication. As part of this, we conduct penetration testing, which are simulated attacks that reveal how real-world threats could exploit your app. Our team provides a detailed report with identified issues, their impact, and practical remediation steps.
Source code review
An extensive review of your application's source code is one of the most effective ways to find hidden vulnerabilities and security flaws. Our source code review service involves a detailed manual and automated analysis of your codebase. We check for issues such as poor coding practices, insecure APIs, and coding errors that could lead to security breaches. We identify all potential weaknesses in your code and provide you with actionable recommendations on how to address them.
ISO 27001/SOC 2 compliance
Our regulatory and compliance security audits focus on ensuring that your application adheres to security standards such as ISO 27001 and SOC 2. These audits help assess your application’s security posture in relation to the regulatory frameworks that govern your industry. We provide a detailed assessment of your current security practices and offer guidance on how to meet the necessary security controls to achieve certification and ensure that your app is compliant and ready for audit.
Implementation guidance for security best practices
Even the most secure application can be compromised if an organization does not follow best practices during implementation. Our implementation guidance service provides your team with detailed instructions on how to integrate security best practices into the development process. This includes guidance on secure authentication, authorization mechanisms, secure data storage, encryption, and secure communication protocols. We communicate transparently with your development team to ensure that security measures are applied consistently throughout the application’s implementation.

Our Approach to Application Security
Step 1
Initial security assessment
The first step is understanding where your application stands in terms of security. We assess potential threats, identify weak points, and evaluate the risks associated with your app’s functionality and data. Working closely with your team, we create a clear roadmap for mitigating these risks and ensuring a solid foundation for security.
Step 2
Code and architecture review
Once we know the risks, we plunge into your application’s architecture and source code. Our team looks for common vulnerabilities like insecure APIs, hardcoded credentials, and improper access controls. We provide a comprehensive review and highlight areas that need improvement to strengthen your application against attacks.
Step 3
Threat modeling and analysis
Next, we map out your application’s components, data flows, and external interactions to identify possible attack points. Analysis of potential threats and attack vectors helps us develop tailored strategies to reduce security risks and enhance your application’s defenses.
Step 4
Security testing and vulnerability detection
We perform static and dynamic security testing to uncover issues in both code and runtime. SAST checks your source code early for vulnerabilities, while DAST simulates real-world attacks on the running app. We also test your APIs for flaws in authentication, authorization, encryption, and input validation. To go deeper, our team conducts penetration testing using both automated tools and manual methods. This helps uncover risks like broken authentication, insecure data handling, and session mismanagement. Together, these tests reveal critical security defects before they can be exploited.
Step 5
Secure development integration
Security should be embedded in development from the start, not tacked on at the end. We help integrate security practices into your SDLC, including secure coding guidelines, code reviews, and automated security testing. This proactive approach reduces security vulnerabilities and minimizes costly fixes down the line.
Step 6
Compliance and regulatory alignment
For businesses handling sensitive data, meeting industry security standards is critical. We help you align with frameworks like ISO 27001 and SOC 2. Our experts conduct security audit preparation, assist with compliance documentation, and ensure your application meets regulatory requirements.
Step 7
Remediation guidance
Finding vulnerabilities is just the first step – fixing them effectively is what matters. We provide clear, actionable remediation guidance and work with your team to implement necessary security patches. Afterward, we validate the fixes to ensure they resolve the security vulnerabilities without introducing new risks.
