Security Assessment &

Penetration Testing

What is Security Penetration Testing? 

Penetration testing is an imitation of attack actions of a malicious user on a computing system , web application, back-end API, or underlining network infrastructure by a team of white-hat hackers.

Many buzzwords are often related to penetration testing, including ethical hacking, vulnerability assessment, and security testing, assessment, or assurance.

The reason to try penetration testing is to gauge the extent of security of a system by exploring vulnerabilities of gaining access or control over critical systems and data that might impose the threat of losing financial assets or critical data.

It should be noted that compliance and regulatory requirements, like Payment Card Industry Data Security Standard (PCI DSS) or General Data Protection Regulation (GDPR) requires organizations to undertake regular testing to gauge the effectiveness of organizational security controls.

It stands to reason that the further an adversary can penetrate into your organization and retrieve sensitive and/or tip, the more evident the business case for improving your cybersecurity posture becomes.

zerOxImpact uses an open application security standard for web apps and web services of all kinds. OWASP standard provides a basis for designing, building, and testing technical application security controls, including architectural concerns, secure development lifecycle, threat modeling, agile security including continuous integration/deployment, serverless, and configuration concerns.

Our Value Proposition for Your Cybersecurity Resilence

Website and Application-Layer Penetration Testing

For a mean user, an internet application may be a client-server program during a browser. For a black hat hacker, an internet application is a chance to steal delicate data.

Cyber attacks on web apps range from targeted database manipulations to large-scale network disruptions. Some companies never get over significant data breaches. Flawed coding or failure to sanitize input to and output from web applications may result in massive financial losses, damage to brand reputation, and loss of customer trust.

According to research by Gartner, an estimated 70% of all security breaches are thanks to vulnerabilities within the online application layer. Security mechanisms like firewalls provide little or no protection against attacks on your web applications. Flawed coding or failure to sanitize input to and output from web applications may result in massive financial losses, damage to brand reputation, and loss of customer trust. Therefore, every company should make sure the web security: the simplest way is to rent a white hat hacker.

Why do web pentest?

Web application security testing provides a considerable reduction in risk to your organization in addition to an increase in confidence in the use of your application.


Our Application-Layer Penetration Testing delivers detailed results that include criminals’ attack simulations showing how an attacker can exploit a vulnerability. We combine automated and manual penetration testing to realize the foremost accurate result. Automated tools and scanners discover most technical vulnerabilities, while a penetration tester identifies logical vulnerabilities.

Mobile Application Testing

Viruses, man-in-the-middle attacks, or ruined reputation as a result of a knowledge breach, which might you choose?

zerOxImpact suggests mobile app security testing

Mobile applications are one of the foremost widely spread tools for storing sensitive information as modern people use mobile apps to access the company’s services. It’s imperative to make sure security at both ends. Mobile penetration testing is the solution to make sure that your client won’t fall victim to a positioned attacker who aims to control traffic.

It is pointless to develop a beautiful app if there are holes within the servers that store and process customer data. At an equivalent time, completely secure servers cannot save customer data from retrieval or redirection to a foreign attacker if an app is insecure.

Benefits to do mobile pentest

Mobile application security testing provides a substantial reduction in risk to your organization added to a rise in confidence within the use of your application.

Solution we offer

The testing of mobile applications requires the utilization of an iterative process whereby all testing must be conducted on both iOS and Android devices and across all supported OS versions.

Our mobile app penetration testing provides an insightful security analysis of phone and tablet-based apps. A well-balanced combination of automated and manual penetration testing helps achieve the foremost accurate assessment compared to other pen testing companies.

Cloud Penetration Testing

Cloud penetration testing is different from traditional penetration testing, a bit like cloud architecture/infrastructure is different from old-style on-premise architecture/infrastructure. Cloud providers like Google Cloud Platform (GCP) offer many features/services. Generally follow a shared-responsibility model, where the cloud provider is responsible of the safety of the cloud, like security concerning hardware and backend infrastructure, and you’re responsible for protecting applications and services within the cloud, like as configurations of your servers, privileges granted within your environment, and other.

Why Cloud Penetration Testing?

Cloud environments are often compromised during a sort of way and misconfigurations which will leave you susceptible to external attackers. They aren’t the sole potential threat though: internal employees should be closely monitored also for a couple of reasons, including potential for his or her own malicious activity, their potential for compromise from an external attacker (separate from an immediate cloud environment compromise), or maybe their potential for creating mistakes that open a security hole or perform an unintended action.

The assessment will make sure that the safety of an organization/environment is that the strongest it is often within the unfortunate event that a malicious actor gains unauthorized access.

Network Penetration Testing

The role of servers, employee devices, and routers is typically underrated when it involves corporate security. the target of a network penetration test is to spot exploitable vulnerabilities during a working environment,, hosts, peripherals, other network devices. Black-hat hackers target anything that stores, processes, and transmits sensitive data. it’s unlikely that the corporate user is conscious of the risks connected with his/her WI-FI router. However, a mature company should take into consideration all possible hackers attack vectors. A company’s network could also be under significant risks thanks to a good range of security flaws, including misconfiguration of appliances, outdated software or operating systems, insecure protocols, and unnecessary exposures.


Network penetration test provides comprehensive testing of a company’s servers and network infrastructure to make sure that the corporate is protected against a variety of cyber threats. zerOxImpact white hats will check whether the organization has any exploitable vulnerabilities in networks, systems, hosts and peripherals.

Engaging vulnerability assessment companies may be a step before black hat hackers. we’ll reveal possible opportunities for hackers to compromise systems before they’re ready to exploit them.

What is Penetration Testing Methodology?

Our approach to delivery Penetration Testing


Identify Objectives and Threat Modelling. We want to learn about your application’s use cases. For us critical to understand the types of bugs that are possible in the code we’re reviewing.

By review design documentation and mapping data flows we understanding the context, relationships between an application’s components.

Now it possible to identify design flaws, critical components, or other modules that need a closer look, we can set clear objectives, and keep focused during code review.

Using precise tools is vital to the success of secure code review. A static analysis tool can be used to automatically check code for a set of rules and best practices that you’ve predefined. Automated tools scan in fast and efficient way, and can detect low-hanging fruits and number of other vulnerabilities; there are no silver bullets in a list of tools, and used tool depends on used programming language. 

Automated static

code review


Code Review

For the next pass-over we are reading source code line-by-line in an attempt to identify rest of flows. It is a tedious process that requires technical skill, experience, and patience.

Vulnerabilities discovered and subsequently addressed through the manual review process, can significantly improve an organization’s security posture.


 Once you’ve completed code review, the next step is to priorities the vulnerabilities in order of importance, to ensure that the most severe vulnerabilities highlighted in the overall list. Then you can fix the bugs we’ve identified. Findings give your developers a great starting point when looking for common bugs and vulnerabilities in your code. This knowledge dramatically improves the code they write in the future.

Frequently Asked Questions.
Here are some common questions about Security Assessment

Is penetration testing dangerous?

Penetration testing is that the process of identification and exploitation of vulnerabilities. Often a white hat conducts testing without causing damage to the tested resource. there’s always alittle chance that testing may provide some negative influence on the tested system (DoS, data corruption or removal). that’s why it’s recommended to perform any actions after working hours.

What is the various sort of penetration testing?

There are three sorts of penetration testing supported provided data and knowledge from a customer: White, Gray, and black-box pentest.


  • With the black-box model, pentesters have limited knowledge of the network and no information on the customer’s security policies, network structure, operating systems, and network protection. With limited details available, an ethical hacker has got to penetrate the network as profoundly as possible to detect the hidden vulnerabilities.
  • White-box assumes that a white hat has admin rights and access to configuration files or maybe ASCII text file of application or services. Pentesters have access to server configurations, communication logs, and database encryption principles.
  • Grey-box penetration testing combines two approaches described above. A white hat receives certain details about the network, like user login details or the overview of the network. Notably, when testing an internet app, a pentester tries to get potential entry points.
What are penetration testing tools?

Software security testing services use different tools to seek out vulnerabilities. the foremost popular vulnerability scanners for websites are Acunetix, BurpSuite, OwaspZAP. For manual pentesting of internet sites and certain pentesting operations with mobile applications, pentesters use automatic tools, such as, BurpSuite: it allows us to intercept scanning requests and edit them. For local networks, the foremost popular scanners are Nmap and its modifications with GUI Zenmap, Tenable Nessus, Rapid7 Nexpose, and Retina. To verify the vulnerabilities, you’ll use the Metasploit, Empire, and other tools.

What is the price of penetration testing service?

The cost of the pentesting is unique to every client. Several parameters influence the price: the number of resources to be audited, the timeframe, and complexity of the work.

How much time does penetration testing take?

The timeframe is different to every client. It depends on the complexity and therefore the breadth of labor. Approximately it takes between 2 and 4 weeks for common systems to be tested.

Do you give recommendations regarding possible fixes to the bugs?

In the report, we give brief recommendations regarding possible responses to a bug or a vulnerability. If you would like advanced recommendations or clarifications regarding the severity of vulnerability, you’ll email us.

What is considered a “significant change”?

Significant change — for example, infrastructure or application upgrade or modification — or new system component installations. What’s deemed “significant” is very hooked into risk assessment process and on the configuration of a given environment.

Is there an alternate to pentesting?

Our bug bounty program HackenProof is an alternate to pentesting during a long-term perspective. It’s important to know the difference between a pentest and therefore the bug bounty program. One team performs penetration testing, and it aims to explore the state of security of a system or an application at a specific time. When it involves HackenProof, we perform endless in-depth check of system vulnerabilities. However, researchers are limited to bounties that they’re paid.

What is a Red Team?

Many security assessments specialize in breadth, instead of depth and are constrained to the given component being tested. Red Teaming is an adversarial goal-based assessment that gives a real-world view of what an attacker would do to compromise your organization’s assets.

A Red Teamer won’t solely specialize in just your network infrastructure or web applications, instead of determining which systems to check, it’d be simpler to stipulate what’s not in scope.

A Red Team engagement team of consultants will identify potential weak points and string together seemingly unrelated vulnerabilities to make composite attack scenarios.

What are the restrictions of penetration testing?

Penetration tests will help test your security readiness, but it’s not a panacea for all ills. For example, a penetration test:

  • Covers target application, infrastructure or environment that in scope
  • Focuses on the exposures within the technical infrastructure
  • Is only a snapshot of a system at some extent in time
  • Can be limited by legal or commercial considerations, limiting the breadth or depth of a test
  • May not uncover all security weaknesses, for instance, thanks to a restricted scope or inadequate testing

It provides results that are often technical and wish to be interpreted during a business context.
