When it comes to cyberattacks, everyone believes it couldn’t happen to them until it does. This far-off concept became a real nightmare for LastPass, a password management software, in August 2022 and again in April 2024.
These attacks resulted in customer information, such as passwords to different platforms, being used to siphon over $4.4 million worth of cryptocurrency and sell the data on the dark web, compromising the privacy of a huge part of their customer base.
To stay ahead of cyber threats in a rapidly growing SaaS space, companies should employ cyber security auditors for regular testing to prevent considerable reputational, financial, and resource loss. A cyber security auditor or auditing company fulfills this role by identifying and resolving software vulnerabilities to prevent the risk of data breaches.
What is a Cybersecurity Audit?
A cybersecurity audit is a structured review of your systems, networks, and applications to identify vulnerabilities, misconfigurations, and compliance gaps. It provides an independent, end-to-end assessment of your security posture and documents how well your defenses align with industry standards.

Audit vs. Assessment vs. Penetration Test (Quick Comparison)
- Audit: Formal, compliance-driven review of policies, processes, and systems. Focuses on security controls and evidence.
- Assessment: Broader evaluation of overall security posture. Usually consultative, highlighting risks and improvements.
- Penetration Test: Attack simulation by ethical hackers to uncover exploitable weaknesses that automated tools may miss.
Who is a Cyber Security Auditor?
A cyber security auditor or auditing company conducts vulnerability assessments and penetration tests to find vulnerabilities in your network, systems, cloud, API, and applications that could lead to cyberattacks and data breaches.
A cybersecurity auditor helps:
- Complete Security Posture Evaluation by conducting custom audits covering the entire IT infrastructure, system configurations, access controls, and application security to find vulnerabilities.
- Penetration Testing and Threat Modeling Services use pentesting techniques to simulate real-world attack scenarios and identify weaknesses. They also utilize threat modeling to gauge potential threats and prioritize security controls based on the likelihood and impact of each threat.
- Detailed Reporting and Remediation Guidance is included in the report covering identified vulnerabilities, their severity levels, and remediation strategies.
How Audits Are Performed
- Planning & Scoping: In this phase, you define the systems, applications, and environments to be covered in the audit and scope out the different components of each system that need to be tested.
- Evaluation: Review the infrastructure, configurations, access controls, and development practices, including their current security standing and any identified weaknesses/open ports.
- Testing: Use a combination of automated scans, manual vetting of scan results, and expert-led penetration testing – all of which Astra Security can help you with.
- Reporting & Remediation: Finally, you can go through the findings, which should be given to you with severity ratings by the testing team, conduct compliance mapping to see what misses need to be fixed to achieve compliance, and take actionable steps to remediate the vulnerabilities.
SaaS-Specific Scope (What Gets Tested)
1. IT Infrastructure Assessment
Auditors assess the organization’s IT infrastructure, scrutinizing network architecture, system configurations, and access controls. This approach exposes potential firewall vulnerabilities, intrusion detection/prevention systems (IDS/IPS), and other network security mechanisms.
2. Security Protocol Review
Security protocols, encompassing authentication methods, authorization levels, and data encryption techniques, undergo rigorous scrutiny in a security audit. Auditors identify weaknesses attackers could exploit to gain unauthorized access or manipulate sensitive data.
3. Software Development Practices
The software development lifecycle (SDLC) is evaluated to identify potential security flaws that may have been introduced during development. Coding practices, adherence to secure coding standards, and vulnerability management procedures are assessed to ensure secure software development.
Need for Cyber Security Audits in SaaS Companies
1. Building Trust Among Clients
Trust is a key differentiator in the rapidly evolving SaaS industry that offers a competitive advantage. Customers trust your platform with their data and expect the best data safety practices.
You can strengthen this trust by regularly conducting cybersecurity audits that proactively identify and solve vulnerabilities. A solid security posture also increases investor confidence, creates brand credibility, and attracts security-conscious consumers to expand your clientele.
2. Continuous Testing for Emerging Threats
New vulnerabilities emerge daily, necessitating a security strategy based on continuous testing and consistent updating of the list of tests conducted.
Make it a top priority to find an auditor who combines automated vulnerability scanning, human penetration testing conducted by security experts, and regular updates to its tests. This ensures that you identify known vulnerabilities, zero-day exploits, and emerging threats before they can be exploited.
4. Being Compliance Ready
Security audits serve as a roadmap to achieving compliance with regulations such as HIPAA, GDPR, PCI DSS, and SOC 2, even though getting an audit does not automatically guarantee it.
Audits identify vulnerabilities that might prevent SaaS organizations from complying with regulations. By addressing these weaknesses, they can greatly increase their compliance rate.
5. Prevents Potential Losses
Data breaches continue to cause major financial and reputational damage: IBM’s Cost of a Data Breach Report 2024 found the global average breach cost reached a record $4.88 million per incident, underscoring why regular security audits are a strategic investment to reduce financial, operational, and trust-related risk.
How to Choose a Cybersecurity Auditor
1. Automated Scanning Combined With Pentesting
When we discuss combining manual and automated testing, we don’t necessarily recommend opting for the month-long manual tests. There is a better option.
You should look for companies with a solid automated vulnerability scanning tool and a team of security experts that can validate the results the scanner shows and also look for things it might have missed. By employing penetration testing conducted by security experts
2. Authenticated Scanning
A vulnerability scanner should be able to scan behind login pages and properly test every portion of the network, application, or system. However, most scanners must be authenticated manually whenever a session runs out and cannot scan behind login pages. Find a scanner that offers these features as well.
3. Comprehensive Dashboard
You need an interactive dashboard that lets you manage the vulnerabilities, assign them to team members, monitor and update their status, and even get help from security experts to resolve them. By prioritizing an auditing company that offers a dashboard that can be customized to your needs, you’re making vulnerability management a much simpler process.
4. Actionable Reports
A long and complicated vulnerability report that isn’t customized to the technical level its reader requires doesn’t serve its purpose of communicating details of the vulnerability effectively. A customizable report helps you decide the technical information you want to include to provide a bird’s eye view to a CTO or a detailed breakdown of each vulnerability to a security engineer.
The report’s structure should help you prioritize critical vulnerabilities and guide you in the right direction for remediation.
