We believe in building a relationship with our clients, which allows for a more intimate understanding of the challenges and provides us with the insight to deliver solutions that are fit for purpose.

In the event that information is sourced from external vendors, Nclose will consolidate their advice and opinions into easily manageable documents and reports for your consideration.   Information Security The purpose of Information Security is to protect and preserve the Confidentiality, Integrity and Availability of information. We assist organisations in the alignment of these principles into the DNA of an organisation, this is achieved through various engagement types. We utilize a number of different frameworks such as ISO27001/2, COBIT5 and NIST to provide solutions that are both pragmatic and holistic.   Information Privacy We provide clarity on the minefield that is Information privacy, we can assist with understanding the many requirements associated with the South African Privacy legislation (POPI) and deciphering them into something meaningful. Providing then a roadmap to compliance.   Information Risk Management Information Risk Management is the foundation upon which Information Security is based. Risk management is the mechanism by which decisions are made regarding security, decisions that are based on understanding the unique risk exposure of each organization. We at Nclose are able to articulate Risk in a language that is meaningful to both Business and IT, thereby navigating the complexities associated with this complex discipline.   Business Continuity Management Our approach to Business Continuity is aligned with global best practice and allows Nclose to deliver pragmatic solutions addressing even the most complex of environments.   IT Governance  Nclose can assist organisations with aligning IT and decisions that are made within IT, with Business Objectives/strategy, ensuring that these decisions are made in line with the Business Goals.   IT Service Management  Nclose are able to provide the full spectrum of ITSM services, ranging from Change, Incident and Problem all the way to Portfolio and Project management.  
> Security Analysis and Testing
Security Assessment By combining our innovative range of service, Nclose offers complete security audit facilities designed to suit your needs. Stock rooms, accounting ledgers and other business disciplines are regularly scrutinised; why not audit your information technology security too? While we specialise in tailored audit solutions, we are also able to apply a high-level security assessment that quickly points out areas of concern that may need additional assessment. High-level security assessments also point to the areas where your budget is best spent – guaranteeing maximum return on your IT security investment. For more on our High-Level IT Security Assessment, contact us to discuss your requirements in detail. Vulnerability Assessments Vulnerability assessments assist in ensuring that all software applications on your network are patched, up to date and securely configured. Nclose performs vulnerability assessments on a regular basis, as and when required by your organisation. Our line-up of test tools and applications includes open source as well as commercial solutions – ensuring that as many possible forms of attack and deviance are checked for during each assessment. Penetration Testing Penetration testing takes vulnerability assessments to the next level by attempting to breach your network’s boundaries. This may sound counter-productive, but penetration testing stresses your network security in a realistic manner, while simultaneously giving you insight into your immediate risks. Nclose’s customised approach extends well beyond conventional attack methodology, delving deep into the fast developing threat that social engineering poses to your network resources. Ensuring that your test is the real deal Penetration testing is easily confused with vulnerability testing, and unscrupulous security firms often sell inadequate solutions that leave their clients open to network attacks from in- and outside their organisations. In penetration testing there is no grey area. It’s all black and white. Nclose offers unique black- and white-box testing that approaches your network from commonly used avenues. Black-box testing simulates attacks that are based on a complete lack of information on your network. These attacks are typically mounted by hackers that know what they want, but know nothing about the environment in which it is hosted. White-box testing simulates attacks that people inside your organisation may plan, or assist with. Disgruntled employees, or spies, may pass essential network information to hackers, or use it themselves to penetrate your network for various reasons. A combination of these testing protocols easily identifies areas of your network that require additional protection and strengthening, as well as existing areas of strength that can be used as building blocks for complete protection. Network size is no longer a determining factor Penetration testing is not simply for large networks belonging to large organisations. Small organisation are equally vulnerable and often used as pathways into larger networks, making protection against attacks essential. Nclose understands this priority and offers a variety of innovative and competitively priced solutions that allow affordable testing of any network – regardless of size or budget. Contact our team of consultants to discuss your requirements, or for more on a solution that fits your budget.
> Security Solution Management
Service level and maintenance agreements No matter the size or scope of your network, Nclose is ready to help you extract real value from it. A professional evaluation conducted by our security consultants will help you understand how Nclose can help raise your IT security parameters to the level they should be operating at – with constant respect for your budget. Once an understanding of your requirements and budget has been reached, several pre-defined packages are available to you; featuring dedicated amounts of on-site, remote and emergency visits, and reporting. All our reports are individually customised to your needs and are essential tools for auditors and decision makers alike. And if one of our defined packages doesn’t fit your needs, we’ll work together with you until you are happy that you are achieving maximum benefit and cost-effectiveness. Solution Management Many organisations are not able to justify the expense of a dedicated IT security engineer, often resulting in unnecessary IT burdens being placed on unqualified staff members. Ultimately this approach exposes your company to vulnerabilities at several levels – including IT security. Nclose provides professional advice and management of network firewalls, content filters, and other security solutions. Whether your organisation simply requires a once-off advisory consultation, the initial configuration of a new or existing security solution, or regular maintenance and reporting, Nclose ensures that your IT security environment is operating at maximum efficiency.
> Security Policy Consulting
Security policy consulting Security policies are the cornerstone of any organisation’s security strategy. Without policies in place, mechanisms that have been installed or agreed to lose their effect, laying your operations bare to accidental and intentional harm. Auditors will often be the first to point to the lack of policies as one of your organisation’s largest weaknesses. And the task of developing, agreeing to, and finally documenting and applying policies is a time consuming and arduous task. Many companies relent and resort to borrowing other organisations’ policies to use as their own. This practice is riddled with problems, the largest being the individual nature of your organisation. Furthermore, company changes and the introduction of new technologies often introduce new challenges that need to be addressed at policy level. Extensive experience with policy formulation and implementation means that Nclose will manage your policy process from start to end – and beyond; reviewing and updating policies on a regular basis to ensure that all avenues are covered. By applying industry best practices and calling upon the services of specialist IT legal representatives, Nclose is able to guarantee that your policies comply with all existing legal parameters, and will protect your IT environment from any and all applicable legal irregularities. Legal Disclaimers and Terms Nclose also consults on the creation and implementation of email disclaimers, website terms and conditions, privacy policies and issues relating to the RICA, ECT and other up and coming Bills and Acts.

20% product + 80% Nclose = 120% benefit

Product selection is simply the start of the Nclose journey. It’s our ability to push new and existing solutions past the point of value realisation that sets us apart. As with any tool, expert human intervention is often required to ensure proper implementation and the extraction of maximum value. The same applies to IT security solutions, turning your IT security investment from an expense into an active contributor to the bottom line.

Stephen Olser
Business Development Director

Stephen started his professional career in London at eBookers.com where he assisted in the growth and development of an online booking product. This experience marked the beginning of his passion for IT, and his entry into a career in the field. Being proudly South African and optimistic about our country’s future, he returned in early 2004 where he joined the local IT security industry. His first post was at a large IT security solutions distributor where he spent four years. During this time his IT Infrastructure and security solutions knowledge grew substantially. As well as developing a sharp focus on product perfection and client satisfaction, he also grew his determination to fulfil the market ‘gap’, hence his current involvement with Nclose. His passion for customer service has led to strong relationships with customers from across the IT security industry, including many of the Fortune listed companies of Southern Africa.

Martin Potgieter
Technical Director

Martin has extensive experience in a wide range of network and system technologies, both open source and proprietary.
He has a passion for IT security which was sparked in 1999 when he installed Snort for the first time and noticed over 50 000 attacks after just one weekend of monitoring. Since then Martin has gradually become more involved in the information security industry.
Since helping establish Nclose in 2006, Martin has gained further experience and developed a keen interest in building and running a business from the ground up. Being able to bridge the gap - and identify the right balance - between business and risk has been a key factor in his success. Martin’s ability to communicate at all levels, and his hands on approach, are key ingredients in his recipe for success. A “techie” with good communication skills is a rare combination.
