Cheyenne Software and Intrusion Detection form security partnership.

ROSLYN HEIGHTS, N.Y.--(BUSINESS WIRE)--October 15, 1996--

Companies Integrate Windows NT Network Security Products -- InocuLAN

and Kane Security Analyst

Cheyenne Software, Inc. (AMEX: CYE) today announced a strategic alliance with Intrusion Detection, Inc., a network security software developer. The alliance kicks off with the integration of Cheyenne's InocuLAN network antivirus solution and Intrusion Detection's Kane Security Analyst (KSA). As the established standard among security auditors and network professionals, KSA is now able to assess network virus protection in addition to overall network security.

KSA includes a new Antivirus option which generates audit reports identifying exactly which Windows NT servers and workstations on the network are not using InocuLAN virus protection. Those computers not utilizing InocuLAN are susceptible to virus infection which can result in lost data or significant user down-time. Cheyenne is now shipping an evaluation version of KSA with InocuLAN 4 for Windows NT.

"Administrators today are very aware of the importance of virus protection on the network but are looking for tools which will lighten the administrative tasks associated with providing that protection," said Paul Mason, an analyst at International Data Corporation. "The integration of InocuLAN and KSA will provide network security professionals with a valuable tool for reporting on the level of network security and virus protection employed on the network at any given time."

Additional efforts are currently underway at Intrusion Detection to further expand the integration of the products by incorporating InocuLAN virus scanning statistics into the KSA audit reports. These features will provide KSA users with detailed information about the type and frequency of computer viruses found on the network. The companies are also planning to integrate KSA with Cheyenne's storage management products which include ARCserve 6 for Windows NT and NetWare.

"Security users will get real mileage from these products working together. It is the logical integration of security assessment with both virus and backup protection," commented Robert Kane, president of Intrusion Detection.

KSA

Intrusion Detection's KSA is the only product for Windows NT and NetWare which performs a complete network security health check and reports the findings in easy-to-understand reports. KSA is able to report on network security in six main areas: password strength, access control, system monitoring, data integrity, data confidentiality and user account restrictions.

The KSA audit reports utilize a built-in knowledge base which contains an extensive list of known NT security vulnerabilities. The end result is a fast and complete report which details network security vulnerabilities and suggests how they can be fixed. More information about KSA can be found at http://www.intrusion.com.

InocuLAN

Cheyenne's InocuLAN is the leading antivirus solution for Windows NT and NetWare with a host of unique features designed to simplify network virus protection -- including enterprise domain management, automatic network updates and options to protect messaging servers such as Lotus Notes and Microsoft Exchange Server.

InocuLAN offers advanced virus detection capabilities and is certified by the National Computer Security Association (NCSA) to detect 100% of viruses in the wild. Additional product information is available at http://www.cheyenne.com/security.

"During 1996, an average corporation with 1,000 PCs will have 10 computer virus incidents per month," said Dr. Peter Tippett, president of the NCSA. "This is at least five-fold more prevalent than last year. And most Local Area Networks are configured with susceptibilities to many other kinds of security breaches beyond viruses which can be detected with tools like KSA. It makes sense to check a network for relevant security problems and to assess the extent of virus protection at the same time," Tippett added.

Pricing and Availability

Cheyenne's InocuLAN 4 for Windows NT servers ($995 retail price) is available from resellers and distributors worldwide. Now included with InocuLAN is a 60-day evaluation copy of Intrusion Detection's KSA for Windows NT servers or workstations. Both versions are compatible with Windows NT 3.51 and 4.0. KSA for Windows NT is available for $495 directly from Intrusion Detection.

The letter of intent signed by the companies is non-binding and the relationship is subject to the execution of a definitive agreement.
