What is Vulnerability assessment and penetration testing (VAPT)?

Vulnerability Assessment and Penetration Testing or VAPT are two important processes which involve scanning of the network, detecting its risks or vulnerabilities and thereby mitigating the same through various systematic procedures. Vulnerability assessment analyses the security weaknesses in overall network and suggests the level up to which a network can be attacked by a malicious intruder. Accordingly a detailed report is generated and mitigation strategies are planned. VAPT is an essential step in security because it generates trust of the customer in an organization and certifies it as a secure service provider. 

The VAPT testers from Delta Safety services are familiar with different ethical hacking techniques such as Foot printing and reconnaissance, Host enumeration, Scanning networks, System hacking Evading IDS, Firewalls and honeypots, Social engineering, SQL injection, Session hijacking, Exploiting the network etc.

Information Gathering

The penetration tester of a Delta Safety services provider locates publicly-accessible information related to the client and finds out ways which can be exploited for getting into systems. The tester employs tools like port scanners for completely understanding the software systems in a network. With the use of this information, tester pinpoints different findings’ probable impact on the client.

Planning and Research

After information collection through several informational tools or manual surfing, next stage demands planning and thorough research. The planning process is initiated by defining penetration testing’s objectives. Goals are then defined jointly by tester and client so that both parties have the same level of understanding and objectives.

Vulnerability Detection

Testers of the right online VAPT provider understands the response of a target app to several intrusion attacks. Static as well as dynamic analysis is used in this situation. The former method is used to check whether the application code is behaving in the exact way it should be while running or not and the latter one involves its inspection in the running condition.

Penetration Testing

It utilizes web app attacks like cross-site scripting, backdoors, and SQL injection for uncovering a target’s vulnerabilities. Then, the testers try for these vulnerabilities’ exploitation to comprehend the destruction that they can cause.

Access Control

Access control is the only technology that actively attempts to keep unauthorized individuals out of a access area or within a facility, and is a complement to video surveillance, burglar and fire systems.

Report and Analysis

The test’s result is consolidated and compiled into the report that briefs the sensitive data accessed and particular vulnerabilities exploited etc. This report is analyzed by security personnel to create strong safety solutions.

Difference between vulnerability scan & penetration testing?

     Web security testing services, also called as VAPT includes Vulnerability scan or vulnerability assessment, to find out known vulnerabilities in a system. Vulnerability assessment tools are used for assessment. They help identify the vulnerability but do not distinguish between flaws that can be exploited to cause damage and those that cannot. Scanning is done continuously, especially after new equipment is loaded. Vulnerability assessment focuses on:
• Identifying potential vulnerabilities
• Classifying vulnerabilities into High, Moderate, and Low risk vulnerabilities.
• Identifying assets connected to the network.
     Penetration tests also called pen test is an attempt to exploit the vulnerabilities in a system. This is done in the way that hackers use in order to exploit the system vulnerabilities. This is done at least once in a year. This helps us to determine whether unauthorized access or other malicious activity is possible into the system and also identify which flaws pose a threat to the application. The goal of a penetration test is to identifying actual risk. Pen test focuses on:
• Identifying unknown vulnerabilities ? zero day?
• Validating vulnerabilities by exploitation
• Identifying additional vulnerabilities not identifiable or accessible by a vulnerability assessment

Benefits for Web Application Penetration Testing?
According to various reports, over 70% of the attacks, in recent times, occur at an application level. As per several surveys conducted over the years, people are attacking through apps in the 21st century as it is easier than via network layer. Despite the common use of defenses like prevention systems or intrusion detection and firewalls, hackers are still able to pose major legal liability without even being detected or stopped. Although there are numerous advantages of Web Application VAPT, some of the major ones are – 

• It secures the sensitive data from getting stolen
• One of the obvious benefits is that VAPT prevents your website from any potential threats
• Not only it gives you short-term security benefits but also proves to be helpful in the future as well
• Any unnecessary capital loss can easily be avoided with the help of VAPT.
• Once you start availing the services of VAPT, you will see a substantial surge in ROI.   

Clients get benefitted from Delta Safety services as it offers a complete analysis of the existing security posture and a suggestion for reducing the exposure to currently recognized vulnerabilities are also highlighted. Hence, the clients can make informed decisions and manage the exposure of dangers in a better manner.


Web servers and the application code running on those as a simple website or web portal, are vulnerable to various attacks. In one type of attack, the hacker can simply deface the pages, while in other serious types, the attacker can potentially steal data and disrupt website operations.
Web security testing is especially important in case of e-commerce based portals, wherein the entire business relies on website and its data contents. In case of recent trend the websites cater to mobile based applications which demands for an end to end testing for total app security. Its important to understand that merely having firewalls and Layer-7 devices are not enough because those cannot detect code level vulnerabilities, and hence a detailed website VAPT is highly recommended.



DELTA should be your first choice when it comes to choosing the services of VAPT as it makes sure that you are only provided with the best level of security –
