SF-Sherlock optimizes maximum mainframe security and compliance as your all-in-one solution in detecting – alerting – combating and monitoring. DORA and NIS-2 readiness never been so efficient to implement.

Your mainframe platform is finally actively protected to the max by our maximum security software SF-Sherlock – a single, integrated, plug & play auditing solution. SF-Sherlock’s all-inclusive real-time configuration and event auditing software does it all. It detects, verifies and/or blocks suspicious behavior, manipulation, and fraud in both the dynamic and static functions of your entire system.

Only a few markets, like here that in Switzerland, can boast of maximum or extraordinary information protection laws and requirements. For more than a decade, the Swiss financial sector has counted on our unique software solution to both achieve and maintain maximum security.

To achieve and maintain maximum security with SF-Sherlock means:

No MIPS, but value-based fees, including the “software as a service” (saas) option
No “n product fractioning” for optimized budget draining, but a product design customized to your requirements and goals
No support charges based on “egg timers”, but comprehensive premium service

Support of all important security standards, such as BSI Base Protection (“BSI Grundschutz”), PCI, NIST, STIG, ZeroTrust, and more


Easy “out of the box” SIEM integration, such as to Splunk, ArcSight, QRadar and more

In having constantly developed and implemented highly innovative and reliable IT security technologies for over a decade, we provide protection capabilities that are unique worldwide. No wonder we are partners with the world’s largest companies and institutions in successfully achieving and maintaining maximum secure environments.

You are aware of today’s risks and dangers

and therefore place a very high value on maximum IT security to protect your company’s major assets. In the era of the Internet and E-Commerce you want to keep trusting in the idea of »Mainframe = Highest Security«.

You know the current, strict legal regulations and recommendations

such as Basel II, IT Baseline Protection Manual (German Federal Office for Information Security), Sarbanes Oxley (SOX), U.S. DOD Regulations, Gramm Leach Bliley Act (GLBA), KonTraG, RS FAIT 1, HIPAA Security, 95/46/EC Data Protection Directive, etc. and the certification criteria according to ISO or BS. These standards require your company to apply precise, efficient and effective measures for securing all IT-based processes and related audit trails, including the underlying technology, against internal and external attacks. You also need to have clear evidence of relief to customers, shareholders and legislators by proving that everything possible, both technically and legally, has been done to ensure the highest standards in security and quality – also for the purpose of achieving a good [risk] rating. Your goal for your company’s mainframes is to meet all these legal and technical requirements with minimal effort. This allows you to search for a comprehensive solution that works automatically, technically perfectly and highly effectively, and that is legally accepted and audit-secure.

You regard security, quality and cost efficiency as extremely important competitive factors.

You know that only with increased quality and the highest level of automation in your daily work processes can you achieve the required highest level of productivity. Accomplishing this will give you the flexibility and time necessary to meet the actual business challenges and opportunities which the future brings.

You want a single solution

that performs all the necessary tasks, such as monitoring events, examining the weak areas of your system by a constant vulnerability assessment, and practically covering the complete technological spectrum of the mainframe platform. At the same time, at your desired level of increased value, this solution should allow for daily application and organized cooperation from all different departments, from the technical level up to the highest level of management.

You also demand openness to integration

into company-wide, cross-platform security management and audit solutions. You never want to doubt your investments in these areas. The solution you aim for should indeed consistently support your interests, also within the scope of ITIL, COBIT, BS7799, ISO 27001, DORA, NIS-2, among others.


SF-Sherlock Real-time security and Quality Monitoring


SF-Sherlock represents the high performance real-time monitoring technology for establishing complete security and quality automation on the z platform by integrating the monitoring, recording, notification, reaction, reporting and possibilities for simulation (e.g. IPL) into an overall solution. With its components, SF-Sherlock is a constantly running system process that monitors and examines the security system (Security Server or RACF as well as CA-TopSecret and CA-ACF2), specific processes and subsystems (DB2, LDAP, etc.) as well as the z/OS operating system with all its components. It records relevant changes in an audit-secure manner and informs the person concerned just in time and specifically about area-related events, such as errors, attacks, manipulations, changes, etc., for instance by e-mail or SMS. The auditing department correspondingly achieves continuously automated monitoring and rating, including reporting. This means no one has to manually process the results and waste time with routine tasks, since all procedures are fully automated. This gives you freedom, flexibility, and security. SF-Sherlock goes beyond pure reporting in well defined cases. For instance, with its optional automatic and instant reaction, SF-Sherlock throws intruders out of the system immediately. With this constant control and observation, realized as 24-hour protection, you achieve the required top-level of security and quality that lets you take command of your system and reduce costs.

The demand for action can not be denied

Since 2004, the German Federal Office for Information Security (BSI) has gone far beyond the compliance level of the U.S. Department of Defense by openly discussing the risks and defining the necessary security measures for the z/OS mainframe platform in its central security guide, the »IT Baseline Protection Manual«. The key message describes the demand for »using a real-time security monitor for z/OS systems to be able to determine security infringements faster«. Real-time monitoring for only a single isolated security aspect, such as SMF records, is still insufficient. Monitoring the entire z/OS with all its components and complex relations and details is necessary. SF-Sherlock monitors the z/OS system comprehensively and completely, since the dominant danger comes from unnoticed “tricky” procedures and concealed errors in the z/OS, such as for reaching higher authorizations, breaking the audit trail, and obtaining unnoticed access to resources. In this way, professionals can spy on all data by targeted bypassing and manipulating the security system while not even leaving a single SMF or log record. Correspondingly, any unnoticed remaining erroneous system parameter or configuration may question the availability of the entire system, at the latest with the next IPL. Both security and quality deficits equally present catastrophes and must be prevented »at any cost«. Therefore, after each modification performed in the system, SF-Sherlock automatically checks your security system as well as the parmlib and other important system files for any possible gaps and errors. A real-time technology is necessary because the lifetime of manipulation for professional illegal activities is extremely short – detection, prevention through reaction, and the consistent presentation of evidence are not possible any other way. The checklist of possible vulnerability and errors is extensive and can only be fulfilled by completely automated monitoring.

Technology that guarantees success

The automatic and comprehensive security and quality assurance technology of SF-Sherlock fully supports the above mentioned outstanding objectives and lets your mainframe platform comply with all the different legal regulations and requirements. With SF-Sherlock, not only do you meet the necessary requirements, you also accomplish both total quality assurance and comprehensive protection. SF-Sherlock paves the secure way of the future of your business. Constant and complete monitoring and examining, especially at deeper technical levels, are becoming increasingly important with the new z/OS functions (Unix System Services, Sysplex Technology, etc.) and with the new areas ofapplication, such as web servers, data servers, and E-commerce platforms. There is no doubt that standard measures thus gradually seem to be insufficient. SF-Sherlock’s function as an intrusion and extrusion detection system for the defence against internal and external attacks is even more significant as the highest level of protection against the increasing opening of previously closed systems and networks to the outside. With its leading technology, SF-Sherlock is an essential step in attaining a constant, up-to-date level of security and quality for combating these risks.

Productivity that guarantees success

As an automatic real-time process, SF-Sherlock works for the departments of security management and auditing, data and information protection as well as system technology. Furthermore, it integrates them into a common and highly efficient workflow, which leads to higher productivity and significant cost reduction. Through its comprehensive security and quality automation, SF-Sherlock is an integrated solution for the whole company, also in a cross-platform context. Its added value provides the highest profitability and cost effectiveness for everyone involved. With the plug&play implementation concept, you reach this goal and the corresponding work as well as legal relief with minimal time, cost and effort.
