We help you build resilience by driving out cybersecurity vulnerabilities

Cyber attack numbers and sophistication are increasing significantly. Businesses need to manage the residual risks more effectively. All of your systems should be regularly tested to determine how they respond to new attacks and what needs fixing to prevent them. Penetration testing provides crucial information to businesses and helps them identify and eliminate vulnerabilities without disrupting services.

Our experienced and qualified experts ​can help you identify cybersecurity vulnerabilities and protect your infrastructure. We have been at the forefront of providing penetration testing services to clients based around the world – offering not only exceptional technical expertise but outstanding client service.

1- Penetration Testing services: 

HSS's expert penetration testers conduct comprehensive in-depth assessments of IT systems, with the owner’s permission, revealing hidden secrets in the same way as real attackers do. We help to transform the technical findings into immediately actionable remediation steps – aiming to protect your needs and hard-won reputation.

Our penetration testing service involves an active analysis of the asset for any potential security vulnerability. This could result from the poor or improper configuration, both known and unknown hardware or software flaws, and operational weaknesses in process or technical countermeasures. The analysis is carried out to simulate real-life cyber attacks from the position of a potential attacker and can involve active exploitation of security vulnerabilities. We will work closely with you to help identify and eliminate areas of potential risk. Any security issues that are found will be presented to your organization, together with an assessment of their impact, and often with a proposal for mitigation or a technical solution

A pen test will help you:

  • Proactively quantify and reduce business risk

  • Validate the effectiveness of your security safeguards

  • Protect your brand reputation and maintain customer loyalty

  • Avoid costly network downtime

  • Avoid fines while meeting regulatory requirements

  • Get tailored reports to help you prioritize remediation for your business.

2- Penetration Testing and Technical Security:

Our penetration testing experts will check whether your organization is resistant to a variety of simulated social engineering attacks, conducted over the Internet, over the phone, or physically at your premises. Assessments cover the following Operating Systems build against security vulnerabilities:

Microsoft Windows:

  • Microsoft Windows Server 2003 / 2008

  • Microsoft Windows XP

  • Microsoft Windows 7

  • Microsoft Windows Vista


  • Ubuntu

  • Debian

3- Wireless Assessments

Wireless vulnerability testing is important to any organization concerned about its network security. It should be thought of as an extension to an organization’s overall network security and part of any infrastructure penetration test or vulnerability testing exercise.  Our team has built up strong experience in testing wireless security over the years by understanding how various wireless networks are architected and implemented.

This is done by either using the wireless security standards or leveraging wireless security mechanisms, provided by reputable vendors to mitigate risk. We undertake wireless security sweeps throughout the testing process. In addition, we can work from both external and internal points of a company and have the latest tools to facilitate our expertise.

Our tests include (but are not limited to):

  • Reviewing of existing Wireless LANs (detection, security, and encryption features)

  • Identification of rogue access points

  • Packet capture

4- Mobile App and Device Security

With the increase in mobile devices being used in everyday life as well as in corporate environments, there is a heightened demand for the security of mobile applications. HSS delivers comprehensive mobile application security assessments for iOS and Android environments.

These operating systems on tablets and smartphones cover the vast majority of the mobile market share – giving peace of mind to you and your customers by ensuring that your applications are secure.

Analyzing the security of mobile applications

We provide an assessment of all different aspects of a mobile application -  you will receive a robust review of your security environment. We use the latest tools and our consultants are up to date with disclosed vulnerabilities on mobile applications, ensuring that the highest level of results is delivered from our tests. Testing includes but is not limited to:

  • Security of information stored on the device

  • Data sent between the device and the server

  • Security of the back-end server of the application

5- Managed Vulnerability Scanning

Regular penetration testing reports showing either complete system status or changes since your last vulnerability scan are provided by our dedicated security experts. We reduce your administrative and maintenance burdens so you can better focus on protecting your assets and, most importantly, reducing business risk. Managed vulnerability scanning is vital to identify and remediate vulnerabilities within your IT environment before hackers can gain exploit them. And overall can reduce and manage risk on an on-going basis to prevent cyber-attacks on external-facing networks. However, it is recommended to carry out vulnerability scanning alongside regular penetration testing, to ensure all bases are covered.

Vulnerability Scanning helps you:

  • Quantify what exposure you have to attack and the data that is potentially at risk, allowing you to make an informed and proportionate response

  • Protect the confidentiality, integrity, and availability of your network

  • Enhance your business continuity by reducing the probability of a security breach or exploitation of IT assets

  • Comply with existing regulations and any security certifications you hold

  • Verify and evaluate your IT security investments and existing protective and preventive measures

  • Establish a high-level overview of your technical security posture, indicating if any further steps, such as penetration testing or policy reviews, are required.

6- Database Assessments

Database security is a specialist topic that overlaps with computer security, information security and risk management. The database security assessment we provide is about checking various information security controls aimed to protect your database against compromises of their confidentiality, integrity, and availability. The set of our tests checks various types or categories of controls, such as technical, procedural, and physical. We will analyze your database (such as MS SQL, Oracle, MySQL, etc.) and check its configuration, security features, access rights, system and object privileges, and many more.

Database assessments include:

Our penetration testers will simulate attacks onto your database and check its security features from a number of perspectives, which include:

  • Attacks from internal users (authenticated and unauthenticated access)

  • Security of the data within the database (e.g. encryption/hashing techniques used for storing sensitive data)

  • Database hardening and security

  • Protecting sensitive data from privileged users (e.g. DBA)

  • Defense in depth mechanisms

7- Digital ​Forensics & Investigations

Our specialists and consultants are world leaders in the field of digital forensic investigation.  We identify, preserve and analyze any data in any computer, device, or network to help you protect your business from inappropriate data use or data loss. Here at HSS, we have been providing digital forensic investigation services to the public and private sectors for over 5 years. The technical skills of our consultants and their ability to adapt those skills and techniques is proven to suit even the most challenging of technical tasks and investigations. 


We use the latest forensic tools but it is our people who give us the edge over others.

Cyber Investigations

A cyber investigation capability is now an essential component of all organizations that store customer or other valuable data as part of their business. 

The risk of your network being compromised or ‘hacked’ by the presence of malware, or by individuals within or outside of your organization, is growing, and the technical defense mechanisms relied upon over the last twenty years are no longer sufficient.  It is now widely accepted that Antivirus (AV) solutions only identify 48% of threats, so it is vital for today’s organizations to be able to respond appropriately when compromises are detected. Identifying, securing, and analyzing relevant information on live networks today, during or following a cyber-related event, requires specialist skills and knowledge so as to ensure any data loss is permanently halted and the vulnerability fixed.  Isolating the offending piece of technology alone is seldom enough these days to remove the compromise.

Cyber investigations are complex and will include the examination of data from computers, servers, the cloud, switches, routers, and many other network devices.  HSS has the experience and ability to isolate a “rogue” digital footprint whilst gathering evidence of the “cyber event”, all of which is essential to help identify the root cause and to be able to identify malicious intruders.

We provide a full range of Cyber Security Incident Response (CSIR) solutions from advice to data collection, bespoke investigations, remediation, and evidential statements and expert services.

Data Acquisition & Collection

In today’s modern organization, investigations of any sort, commercial disputes, and regulatory reporting typically require simultaneous data collection from various locations.  HSS can support your organization in small and large-scale data collections, wherever your data is stored in the world.

Only trained digital forensic consultants to have the skills and equipment to accurately and quickly acquire large volumes of data without compromising the integrity of the data - or indeed the metadata which is so often essential to the investigation efficiency.  Poor or incorrect data collection methods are known to significantly increase the cost of investigations by as much as a factor of 10.  We have deep experience in collecting volatile and static data from technologies including web, database, and email servers, large-scale storage solutions, virtual environments, and all manner of conventional (and some unconventional) digital devices used by private individuals and businesses.

HSS will, with minimal notice, provide personnel and equipment required for your data and evidence collections both in the UK, Europe, and further abroad.
