Penetration Testing for Startups- A Detailed Guide

We readily associate startups across the world with a culture of speed and adaptability. When the pandemic hit, startups were quick to react, evolve, and capitalize on the situation. They devised ways of managing a fully remote crew, accessed business and customer data from wherever they were, and improved user experience despite all that was happening – thoroughly commendable, all of it.

Agility and speed often have a high price to pay. In the case of startups, the price has often been security. It is understandable that security takes a back seat when you are taking applications online overnight. Hackers understood that as well. 

Indian startups like Unacademy, Big Basket, and Juspay were hacked, and 50 million personal records were stolen and put on sale over the last couple of years. And yes, Penetration Testing for Startups could have prevented or alleviated the crises.

What is Penetration Testing for Startups?

Penetration Testing is an offensive security exercise where security engineers try to break into a system by finding and exploiting certain vulnerabilities. The Pentesters create a report that alerts the target organization about the vulnerabilities along with the risk carried by those. The Pentesting team also prepares a guideline for the remediation of the issues.

Different categories of Penetration Testing

You can divide pentesting into three categories from the pentesters’ perspective. Black Box Pentesting, White Box Pentesting, and Gray Box Pentesting

  • Black Box Penetration Testing

In this type of Penetration Testing for Startups, the pentesters get very little information from the target. The tester can approach the target like a normal user and try different methods to unearth crucial information.

  • White Box Penetration Testing

In this approach, the pentesters receive a lot of internal information like Schema, Source Code, OS details, and IP addresses. This sort of test has a large coverage including file path testing, source code testing, etc.

  • Gray Box Penetration Testing

The tester works with limited details about the target system in this approach. It simulates an external attack where the attacker has unauthorized access to certain internal information. This form is effective yet non-intrusive.

Now, let us find out how Penetration Testing for small businesses is placed in the larger scheme of cybersecurity. 

Formulating foolproof security usually has three steps:

Step 1. You include security in the development life cycle and company culture. Implement certain security measures – website firewall, two-factor authentication, and creating security checklists.

Step 2. You perform internal audits where your security-savvy employees try to find vulnerabilities in the system. You can run malware scans or use an open-source vulnerability scan at this stage.

Step 3. This is where penetration testing comes into play. You employ external security engineers to try and break into your system much as a hacker would. This exposes the security loopholes that a malicious actor could have exploited.

Why Penetration Testing is Important for a Small Business?

As we have discussed earlier, when you are trying to get a lot done in a short period of time, security becomes the last concern. But you cannot have it that way if you are to survive for a long time in the technology business – which is every business nowadays. 

Penetration testing by third-party for small businesses helps detect the vulnerabilities that creep into the system. We will lay down three specific reasons for you that make frequent penetration testing an absolute necessity for startups.  

Penetration Testing for Startups

1. Vulnerability Detection

The first major setback for startups and small businesses in terms of security is accepting the notion that cyberattacks concern only large & famous companies. When you build an application, you stitch multiple other applications, plugins, libraries, & other third-party features into it to make your app more robust.

Now, one of those third-party assets can have a vulnerability putting your app at risk. Pentesting small business security can help detect such vulnerabilities after which vulnerability reports are issued to developers to get them fixed for a robust security posture.

2. Build Trust & Reputation

Pentesting your business and its security comes with the added benefit of building trust and reputation. Regular penetration tests help in the detection of vulnerabilities after any major update, change, or installation of new security measures which can possibly result in security gaps.

Quick detection of such vulnerabilities prompts quick remediation thus increasing your company’s reputation while building trust in current and future customers. This trust & reputation can also translate to an increase in revenue through additional clientele.

3. Compliance

Organizations deal with a lot of sensitive information. Healthcare for instance has large repositories of medical data like sensitive patient data and financial data being generated through various connected devices.

Ransomware pushed into the systems of such institutes can wreak havoc in minutes. Hence regulations like HIPAA (Health Insurance Portability and Accountability Act), SOC2 regulations, and PCI DSS for payment card processing companies are in place.

In every industry, small businesses have to comply with corresponding regulations to gain credibility. Hence penetration testing for small businesses and start-ups has become necessary.

4. Protecting customers from data breaches

It is difficult to put an exact ROI on penetration testing. However, you can measure the cost of data breaches. The average cost of a data breach has been $4.2 million in 2021. 60% of small and midsize companies that faced a data breach failed to bounce back. 

While the financial loss is quite significant, the real devastation for a small company comes as a loss of credibility. Often it is the most basic internal practices that help you protect your customers. It is important to understand what data touches what and what lies in the perimeter and take the necessary steps to safeguard your data.

5. Smooth Scalability

Regularly pentesting and remediating the vulnerabilities found in your business security makes scaling your services in the future less of a hassle. Since continuous pentests and subsequent remediations are carried out, if you decide to scale up your services, existing assets and services would still be secure.

Penetration testing of small businesses ensures scalability by addressing vulnerabilities early on. This prevents potential breaches that could disrupt growth, damage reputation, or incur costly fixes.

The Process of Penetration Testing for Small Businesses & Start-Ups

The Pentest process has 5 distinct phases:

  1. It starts with planning where the pentest team interacts with the target organization. The scope of the pentest is determined in this phase. The target organization shares necessary information with the pentesters.
  2. Then comes the information gathering and reconnaissance phase. The security engineers use a bunch of different tools to gather information about the target. This is the phase where the pentesters try to understand how a website is structured, where the data might lie, and which areas are exposed.
  3. In the following phase, pentesters perform vulnerability scans to find out security loopholes that might lead to exploitation. 
  4. Then the pen-testers try to exploit certain vulnerabilities to understand their severity, the risk it poses to the organization, and how they could be exploited by a malicious actor.
  5. In the final phase, the Pentest report is prepared. It contains a detailed analysis of the vulnerabilities along with guidelines for remediation.

How should a Startup imbibe security in its culture?                 

You need to start thinking about security from the very beginning. Whether you start with 4 founders or five employees, you must build a culture where each of you is aware of cybersecurity right from day one. And you do not need to be a security person to do this. 

Turn security into a core value in how you design your app to how you determine its workflow. Inspire everyone to spend those thirty minutes to do some research, and become aware, and it will pay dividends, even if three years later. The best part is, that you can reach out to ask for help.

Something as simple as exposing credentials on GitHub can cause serious damage, so the conversation around how to keep stuff safe, how to store or retrieve data, or how a hacker could break in, helps. Nothing beats instant threat modeling right at the start by the people who are going to build an application even while trying to get it out there as fast as possible. 

Security Best Practices for Startups & Small Businesses

  • Put more focus on how a vulnerability was fixed and how it is ensured that the vulnerability will not get back than blaming the person responsible for designing the feature.
  • Build internal transparency about vulnerabilities
  • Build security awareness across departments
  • Internal transparency about security
  • Put your security policies out there for discussion. 

Why Penetration Testing for Startups is Always a Win

It is difficult to put an ROI on security. Spending a lot on security without seeing an immediate result can be quite stressful for a company working with dwindling funds. But, hear me out. First of all, if you think security is expensive, you do not want to be exposed to the cost of a hack.

Secondly, as a startup, you always think about scaling. That means, regular updates, new people, fast deliveries, and tons of plugins. The small vulnerability you leave untouched today can cause a massive impact ten years down the line. 

It is also a matter of being more secure than your peers. Security comes up as a point of argument when you try to do business. A VAPT certificate at that point can do your startup a world of good.

One can text a malicious payload into the portal and get it to execute against the administrator. Looking at your DNS, one can find, how is it structured, and what internal assets are exposed. They can figure out If you have load balancers and how they are configured.

It’s a tough world out there, and you want to be prepared. 

How Astra can help?

All this information might seem a bit overwhelming if you are just starting out. Cyber security is complicated, there is no denying that. And it can get expensive depending on how much security you are looking for. However, it is of utmost importance to choose the right security partner early on.

What are the phases of penetration testing?

A penetration test is generally divided in six phases – 1) Planning 2) Recon 3) Scan 4) Exploitation and Post Exploitation 5) Reporting 6) Remediation.

How much time does penetration testing for startups take?

The timeline for penetration testing for startups can range from 4 days to 10 days depending on the scope of the pentest.

How much does penetration testing cost for small businesses?

The cost of penetration testing for small business assets like web & mobile apps ranges between $1,500 to $5,000 and for websites run by small businesses and start-ups, it starts at $2,500.

How often should a company undergo pentesting?

The answer varies with the type of organization. Yearly pentesting is recommended for any organization. For a company handling a lot of sensitive data with internet-facing assets, it is ideal to have quarterly pentest.
