Alexandria – September 22, 2026 – Belitsoft, a custom software development firm, introduces a guide based on the company’s case studies. For more than 20 years, Belitsoft has been offering testing services around the world. The 4.9/5 ratings on Gartner, G2, and GoodFirms from customers who have worked with the company for more than five years best demonstrate Belitsoft’s competence.
Belitsoft employs many security testing professionals with extensive experience in a variety of fields, including healthcare, fintech, e-commerce, edtech, and more. These professionals ensure that all possible risks are promptly identified because they are familiar with the specifics of each business. To mitigate risks and provide secure solutions, Belitsoft’s professionals will evaluate clients’ applications, networks, and APIs.
Security testing is an integral part of a risk management plan. Customers in finance, healthcare, SaaS, and other industries are looking for robust, dependable, and relevant security testing. There are many solutions on the market, but the best decisions are made when customers know their own needs and the range of solutions available.
Stage 1: Recognizing the Need
Security testing is a phased decision-making process. It is driven by pressure, context, and organizational structure. As a result, most clients start with a trigger, not a scope or a vendor list.
This need can come up when procurement requests a SOC 2 penetration testing report from a SaaS vendor, for example. Sometimes the trigger is internal. A minor mistake or near miss, or a customer complaint, can reveal a blind spot. A healthcare provider that experienced a low-level ransomware event, for instance, knows that the next one might not be so low-level. Seventy percent of SMBs have been targeted by some type of breach or attack, and the mindset changes from “not us” to “we’re next.” Sometimes it’s just reputation. A high-profile breach hits the headlines, and the board begins to ask questions. In regulated industries such as finance and healthcare, these pressures come fast and don’t let up.
That’s when clients start doing their research. They read about red teaming, vulnerability scanning, and pen testing. They speak to their friends. They review vendor write-ups, They are trying to determine what is relevant to their infrastructure. They try to understand what kinds of testing are available, what kinds of results they might expect, and what their peers are doing. Soon, the principal questions become apparent: Which tests are needed? Who is supposed to do it? What if we don’t?
Stage 2: Defining Requirements
Fintech, healthcare, and SaaS verticals each have very diverse requirements, and once the need is apparent, the work becomes more specialized and scoping is determined by sector, data sensitivity, and regulatory factors.
Cloud computing is a top priority for SaaS companies, HIPAA compliance and patient data security for healthcare enterprises, and PCI DSS for fintech teams.
Fintech teams start with PCI DSS: annual pen tests are a must, but that’s not all. Financial apps require scenario-based testing, assessment of API surface, fraud simulation and coverage of any system that touches cardholder or transaction data.
Healthcare organizations are concerned about patient data protection, service continuity, and HIPAA compliance. Ransomware resilience is a key priority and phishing simulations are often required for healthcare organizations. Most healthcare IT teams are resource constrained, so testing needs to be surgical, safe and done without impacting care. Many need vendors who understand clinical workflows.
In SaaS, cloud is king. Testing of web and mobile apps, APIs, multi-tenant cloud environments are required. API testing is important, especially for exposure risks such as broken auth or injection.
Fintech needs to demonstrate its defenses against AI-based fraud and complex attack chains. Healthcare needs safe testing that’s surgical and doesn’t get in the way of patient care. SaaS needs to plug into DevOps pipelines and drive actionable outcomes.
Stage 3: Choosing an In-House or Outsourced Model
The structural choice — who will carry out the work — comes after scope and objectives are established. The objective is not to find the “right” model but to establish a sustainable model that suits the actual operational reality.
In-house teams offer total control. Companies can build institutional knowledge and act quickly on insights. However, this control comes at a price. The problem is that good penetration testers are hard to find and expensive to hire and retain. Long-term internal teams can be helpful, especially in regulated or high-risk industries such as finance or healthcare. However, they need funding, leadership support, and constant upskilling to maintain a capable workforce 24/7.
Software testing outsourcing means transferring testing-related tasks to a third party that is not involved in the project (for example, a test specialist or a testing company with QA engineers). Your organization uses outside experts to perform the software testing, and those experts are not part of the internal software development process. Outsourcing any part of the software or the whole program testing to an external testing vendor allows your internal core team. By outsourcing testing to independent testers, you can not only improve product quality and complete QA as quickly as your project or business demands, but also focus on speed to market and manage costs. For example, suppose your business develops complex software, such as multi-module enterprise software or SaaS, but you do not want to maintain a testing team with specialized expertise. Suppose you require a mix of automated and manual testing; security, performance, and usability testing; and exploratory and regression testing. It may be expensive in the long run to hire and retain personnel to conduct in-house testing because the cost of operation exceeds the charges for outsourcing services. The external vendor may be given the testing work fully or partially under a long-term or short-term SLA-based contract, and you can obtain the required number of qualified testing professionals who can assume the required level of responsibility.
To find a sustainable model that suits the actual operational reality, clients make decisions based on five factors: how frequently they need tests, what kind of expertise they lack, what their financial model allows, how much internal context matters, and what they are willing to own versus outsource.
