6 Top CyberSecurity Auditors for SaaS Companies in 2024 [Reviewed]

The regulations around data protection and privacy have continuously evolved to control the practices related to data collection and usage and alleviate the risk of data exposition. Cybersecurity auditors play a central role in the entire scheme of things and will be this article’s focal point. 

What is a Cyber Security Auditor?

A cyber security auditor is a person with the necessary qualifications who can perform the following activities for an organization or a company:

  1. Systematically analyze their security infrastructure with customized audits.
  2. Provide detailed reports about current security infrastructure.
  3. Provide a list of improvements to enhance and modify the security for better asset safety.

Top 6 CyberSecurity Auditors

What is a cyber security audit?

A cyber security audit is a thorough examination of an organization’s security posture – its IT infrastructure, security protocols, software development practices, existing security measures like firewalls, etc.

There can be multiple angles to a security audit. You can hire a security testing company to examine your existing security strength and determine how you’d fare against an attempted hack. You can purchase a vulnerability scanning tool to run external scans to find vulnerabilities and security loopholes in your systems.

Or, you can find a more comprehensive solution like Astra’s Pentest Platform that brings the best of both to the table (we will talk more about this approach later). 

Once you have gotten the security audit done, polished out the rough edges in your security policies, and filled the gaps in your defense, you can go for a compliance audit.

Yes, cyber security audits and compliance audits are often used interchangeably but there are marked differences. We will talk about that too.

Why security audits are necessary for the survival of a SaaS business?

As a SaaS business you build a solution, add something to the digital world, create a thing of beauty and satisfaction, and people who believe in your vision, pay you to align themselves with you. You get signups overnight from across the world while sleeping. 

But sleep evades you as you worry about cyber attacks that can cause a denial of service, burn a hole in the bank, expose your customers’ data, and create havoc out of a tiny loophole in your security. Cyber security auditors bring you peace of mind that you need to scale among other things.

Building trust among clients

It’s important for your clients to feel safe when they share their data with you – they need to know you are compliant with industry standards and taking good care of your software assets against malicious actors. 

Keeping security practices up to date

The cyber threat landscape is changing every week. There were 50 new vulnerabilities every day in 2021. You need to twist and tweak your security practices to stay ahead of the curve. Security audits are the best way to determine the correct course of action.

Being compliance ready

Security audits do not make you compliant with security regulations but they definitely prepare you for the compliance audits. For instance, with Astra’s compliance reporting feature you can identify the vulnerabilities that block certain compliances and focus on remediating those on priority.

Saving big money

Cyber security endeavors are often looked at as expenditures whereas they should be perceived as investments. The average cost of a data breach in 2021 was to the tune of $4 million. That includes the business you lose post the event, the cost of fixing, the cost of circulating the updates, and the penalties payable. 

When you have cyber security auditors conduct regular audits and fix the vulnerabilities periodically, you safeguard yourself from loss and actually unlock the confidence to scale.

What should you look for in a cybersecurity audit provider?

Security audits can be difficult, time-consuming, and expensive. Nevertheless, with the right security audit partner things can be really breezy. 

Some cyber security companies have really figured it out. With them, you will have an easy onboarding, there will be absolute transparency, you will be able to monitor vulnerabilities in real-time, and you will be able to scale the process with ease. 

A combination of manual and automated security testing

When we talk about the combination of manual and automated testing, we’re not necessarily saying that you should opt for the month-long manual tests. There is a better option.

You should look for companies that come with a solid automated tool and a team of security experts that can validate the results shown by the automated tool as well as look for things that it might have missed. 

Authenticated scanning

A vulnerability scanner is pretty pointless if it cannot scan behind logged-in pages. The challenge faced by most scanners is that they have to be authenticated manually whenever a session runs out. Some have figured out a way around it too. Look for companies that offer seamless scanning behind the login. 

An interactive platform to manage and monitor the processes

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. A lot of companies try to offer you this experience, but only a few succeed.

An actionable report

A long, complicated, and boring vulnerability report is worse than the vulnerability itself because you are not going to use the report and yet you have paid a bunch of money for it.

You need a report that is nicely composed for all the stakeholders (executives and developers alike). It should help you prioritize the critical vulnerabilities, and also point you in the right direction in terms of remediation. It should trigger action instead of slowing things down with jargon. 

6 best cybersecurity auditors from around the world

Here’s a detailed discussion of some of the top cyber security auditors. This should help you find the right fit for your business.

On top of that, you can integrate the pentest tool with workflow management tools like Jira and Slack. It allows you to assign vulnerabilities to team members without so much as leaving your daily mediums of communication. 

When a vulnerability is found or fixed, the tool can send an update to a designated Slack contact or group. It’s just neat. 

Contextual collaboration

The security experts from Astra engage in contextual collaboration – they discuss steps for remediation or reproduction of a vulnerability by referring to shared resources and documents. It speeds up the process of fixing vulnerabilities for your developers.

Optimizable for different frameworks

The security audit process is made easier if the security testing tool you are using works well with your development environment. Astra lets you adjust the tool to work for your framework with a few clicks. Astra’s pentest platform is also optimized for single-page apps.

Scan behind the login with Astra’s login recorder

Astra has created a solution for this in the login recorder. You fill up some information to authenticate the scanner once and never worry about authentication. You can learn more about it here.

Compliance specific scans 

Astra’s pentest platform allows you to identify vulnerabilities that are blocking specific compliance. It helps you accelerate the process of reaching compliance readiness.

What is the timeline for a security audit?

If you are looking for a comprehensive security audit including the manual pentest component, it can take between 7-14 days depending on the auditor.

Does passing a cyber security audit guarantee compliance?

How much does a security audit cost?

Depending on the size of your company and the nature of your business, a security audit may cost anything between $5000 and $30000.

How often should I conduct security audits?

It’s ideal to conduct two security audits a year while nurturing a system of consistent monitoring around the year.
