Private Securities Litigation Reform Act of 1995
Safe Harbor Compliance Statement for Forward-Looking Statements


In passing the Private Securities Litigation Reform Act of 1995 (the "Reform
Act"), Congress encouraged public companies to make "forward-looking statements"
by creating a safe-harbor to protect companies from securities law liability in
connection with forward-looking statements. ISS Group, Inc. ("ISS") intends to
qualify both its written and oral forward-looking statements for protection
under the Reform Act.

In addition to the other information in this Quarterly Report on Form 10-Q,
stockholders should carefully consider the following factors in evaluating the
Company and its business, as well as the Risk Factors set forth in the Company's
Registration Statement on Form S-1 as filed with the Securities and Exchange
Commission on March 1, 1999.

To qualify oral forward-looking statements for protection under the Reform Act,
a readily available written document must identify important factors that could
cause actual results to differ materially from those in the forward-looking
statements. ISS provides the following information in connection with its
continuing effort to qualify forward-looking statements for the safe harbor
protection of the Reform Act.


RISK FACTORS

Forward-looking statements are inherently uncertain as they are based on various
expectations and assumptions concerning future events and are subject to known
and unknown risks and uncertainties. Our forward-looking statements should be
considered in light of the following important risk factors. Variations from our
stated intentions or failure to achieve objectives could cause actual results to
differ from those projected in our forward-looking statements. We undertake no
obligation to update publicly any forward-looking statements for any reason,
even if new information becomes available or other events occur in the future.

WE ARE A YOUNG COMPANY THAT HAS NEVER BEEN PROFITABLE

We were incorporated in April 1994 and have only achieved profitability this
quarter. We cannot be certain that we can sustain such profitability in any
future period. You should be aware that we have only a limited operating history
upon which to evaluate our business and prospects. We operate in a new and
rapidly evolving market and must, among other things:

         -        respond to competitive developments;
         -        continue to upgrade and expand our product and services
                  offerings; and
         -        continue to attract, retain and motivate our employees.


OUR FUTURE OPERATING RESULTS WILL FLUCTUATE SIGNIFICANTLY

As a result of our limited operating history, we cannot predict our future
revenues and operating results. However, we do expect our future revenues and
operating results to fluctuate due to a combination of factors, including:

         -        the growth of private Internet-based networks (often referred
                  to as intranets);



                                      -16-
<PAGE>   2

         -        the extent to which the public perceives that unauthorized
                  access to and use of online information is a threat to network
                  security;
         -        the volume and timing of orders, including seasonal trends in
                  customer purchasing;
         -        our ability to develop new and enhanced products and expand
                  our professional services;
         -        the growth in the acceptance of, and activity on, the Internet
                  and the World Wide Web, particularly by corporate,
                  institutional and government users;
         -        customer budgets which may limit their ability to purchase our
                  products;
         -        foreign currency exchange rates that affect our international
                  operations;
         -        the mix of distribution channels through which we sell our
                  products; 
         -        product and price competition in our markets; and
         -        general economic conditions, both domestically and in our
                  foreign markets.


We increasingly focus our efforts on sales of enterprise-wide security
solutions, which consist of our entire product suite and related professional
services, rather than on the sale of component products. As a result, we expect
that each sale may require additional time and effort from our sales staff. In
addition, the revenues associated with particular sales vary significantly
depending on the number of products licensed by a customer, the number of
devices used by the customer and the customer's relative need for our
professional services. Large individual sales, or even small delays in customer
orders, can cause significant variation in our license revenues and results of
operations for a particular period. The timing of large orders is usually
difficult to predict and, like many software companies, our customers typically
license most of our products in the last month of a quarter.

Our future operating expenses are expected to increase in future periods as we
intend to:

         -        expand our domestic and international sales and marketing
                  operations;
         -        increase our investments in product development and our
                  proprietary threat and vulnerability database; 
         -        expand our professional services capabilities;
         -        seek acquisition candidates that will enhance our products and
                  market share; and 
         -        improve our internal operating and financial systems.


We cannot predict our operating expenses based on our past results. Instead, we
establish our spending levels based in large part on our expected future
revenues. As a result, if our actual revenues in any future period fall below
our expectations, our operating results likely will be adversely affected
because very few of our expenses vary with our revenues. Because of the factors
listed above, we believe that our quarterly and annual revenues, expenses and
operating results likely will vary significantly in the future.

WE FACE INTENSE COMPETITION IN OUR MARKET

The market for network security monitoring, detection and response solutions is
intensely competitive, and we expect competition to increase in the future. We
cannot guarantee that we will compete successfully against our current or
potential competitors, especially those with significantly greater financial
resources or brand name recognition.

WE FACE RAPID TECHNOLOGICAL CHANGE IN OUR INDUSTRY AND FREQUENT INTRODUCTIONS OF
NEW PRODUCTS



                                      -17-
<PAGE>   3

Rapid changes in technology pose significant risks to us. We do not control nor
can we influence the forces behind these changes, which include:

         -        the extent to which businesses and others seek to establish
                  more secure networks;
         -        the extent to which hackers and others seek to compromise
                  secure systems;
         -        evolving computer hardware and software standards;
         -        changing customer requirements; and
         -        frequent introductions of new products and product
                  enhancements.


To remain successful, we must continue to change, adapt and improve our products
in response to these and other changes in technology. Our future success hinges
on our ability to both continue to enhance our current line of products and
professional services and to introduce new products that address and respond to
innovations in computer hacking, computer technology and customer requirements.
We cannot be sure that we will successfully develop and market new products that
do this. Any failure by us to timely develop and introduce new products, to
enhance our current products or to expand our professional services capabilities
in response to these changes could adversely affect our business, operating
results and financial condition.

Our products involve very complex technology, and as a consequence, major new
products and product enhancements require a long time to develop and test before
going to market. Because this amount of time is difficult to estimate, we have
had to delay the scheduled introduction of new and enhanced products in the past
and may have to delay the introduction of new products and product enhancements
in the future.

The techniques computer hackers use to gain unauthorized access to or to
sabotage networks and intranets are constantly evolving and increasingly
sophisticated. Furthermore, because new hacking techniques are usually not
recognized until used against one or more targets, we are unable to anticipate
most new hacking techniques. To the extent that new hacking techniques harm our
customers' computer systems or businesses, affected customers may believe that
our products are ineffective, which may cause them or prospective customers to
reduce or avoid purchases of our products.

RISKS ASSOCIATED WITH OUR GLOBAL OPERATIONS

The expansion of our international operations includes the maintenance of sales
offices in dispersed locations throughout the world, including throughout Europe
and the Asia/Pacific and Latin America regions. Our international presence and
expansion exposes us to risks not present in our U.S. operations, such as:

         -        the difficulty in managing an organization spread over various
                  countries located across the world;
         -        unexpected changes in regulatory requirements in countries
                  where we do business;
         -        excess taxation due to overlapping tax structures;
         -        fluctuations in foreign currency exchange rates, which may be
                  aggravated in European markets by the recent introduction of
                  the Euro currency;
         -        export license requirements and restrictions on the export of
                  certain technology, especially encryption technology;
         -        trade restrictions;
         -        changes in tariff and freight rates; and



                                      -18-
<PAGE>   4

         -        depressed regional and economic conditions, such as those
                  currently affecting many regions in Asian markets.


Despite these risks, we believe that we must continue to expand our operations
in international markets to support our growth. To this end, we intend to
establish additional foreign sales operations, expand our existing offices, hire
additional personnel, expand our international sales channels and customize our
products for local markets. If we fail to execute this strategy, our
international sales growth will be limited.

To date, we have primarily denominated our revenues from international
operations in United States dollars; however, we will increasingly denominate
sales in local foreign currencies in the future. An increase in the value of the
United States dollar relative to foreign currencies would make our products more
expensive and, therefore, potentially less competitive in foreign markets. In
addition, even if we successfully expand our international operations, we may
not be able to maintain or increase international market demand for our
products.

WE INCREASINGLY RELY ON INDIRECT DISTRIBUTION CHANNELS

Although our direct sales have accounted for a majority of our revenues in this
quarter, we expect to continue to license a significant percentage of our
products to end users through indirect distribution channels in the future. Our
indirect distribution channel partners include:

         -        original equipment manufacturers that bundle our products with
                  products that they sell to their customers;
         -        managed service providers, such as telecommunications
                  companies and Internet service providers, that host networking
                  and Internet operations for business customers; and
         -        consultants and systems integrators that incorporate our
                  products into customized solutions that they have implemented
                  for their customers.


Our future performance will also depend, in part, on our ability to both retain
the channel partner relationships we have built and attract new channel partners
to market and support our products effectively, especially in new markets. We
cannot assure you that revenue from channel partners that accounted for
significant revenues in past periods will continue or, if continued, will reach
or exceed past performance levels. In addition, we often depend upon our channel
partners to install and support our products for end users. If our channel
partners fail to provide adequate installation and support, end users of our
products could cease using, or improperly implement and operate, our products.
Such a failure could substantially increase our customer support costs and
adversely affect our business.

POTENTIAL FUTURE ACQUISITIONS OR INVESTMENTS

As part of our growth strategy, we have acquired, and may continue to acquire or
make investments in, companies with products, technologies or professional
services capabilities complementary to our solutions. In acquiring companies in
the future, we could encounter difficulties in assimilating their personnel and
operations into our company. These difficulties could disrupt our ongoing
business, distract our management and employees, increase our expenses and
adversely affect our results of operations. These difficulties could also
include accounting requirements, such as amortization of goodwill or in-process
research and development expense.



                                      -19-

WE DEPEND ON OUR KEY PERSONNEL

Our future success also depends on our continuing ability to attract and retain
highly qualified engineers, managers and sales and professional services
personnel. The competition for employees at all levels of the software industry,
especially those with experience in the relatively new discipline of security
software, is increasingly intense.

WE DEPEND ON OUR INTELLECTUAL PROPERTY RIGHTS AND USE LICENSED TECHNOLOGY

We rely primarily on copyright and trademark laws, trade secrets,
confidentiality procedures and contractual provisions to protect our proprietary
rights. We also believe that the technological and creative skills of our
personnel, new product developments, frequent product enhancements, our name
recognition, our professional services capabilities and delivery of reliable
product maintenance are essential to establishing and maintaining our technology
leadership position. We cannot assure you that our competitors will not
independently develop technologies that are similar to ours.

We seek to protect our software, documentation and other written materials under
the trade secret and copyright laws, which afford only limited protection. We
have also submitted two United Stated patent applications. Patents may not issue
from these applications or, if issued, may not provide any meaningful
competitive advantages to us.

Despite our efforts to protect our proprietary rights, unauthorized parties may
attempt to copy aspects of our products or to obtain and use information that we
regard as proprietary. Policing unauthorized use of our products is difficult.
While we cannot determine the extent to which piracy of our software products
occurs, we expect software piracy to be a persistent problem. In addition, the
laws of some foreign countries do not protect our proprietary rights to as great
an extent as do the laws of the United States and many foreign countries do not
enforce these laws as diligently as U.S. government agencies and private
parties.

We are not aware that any of our products infringes the proprietary rights of
others, but it is conceivable that our current or future products may infringe
the proprietary rights of others. In fact, in July 1998 Network Associates, one
of our competitors, filed a lawsuit against us alleging that our Real Secure
product violates a patent claim for intrusion detection technology held by
Network Associates. We believe that the lawsuit is without merit and are
vigorously defending against Network Associates' claims. However, should Network
Associates prevail in the suit, it could materially and adversely affect our
business.

We expect the number of intellectual property infringement lawsuits against
software companies to increase. Any such claims, with or without merit, could be
time consuming, result in costly litigation, cause product shipment delays or
require us to enter into royalty or licensing agreements.

WE LACK CERTAIN TRADEMARK PROTECTION

We currently cannot obtain trademark protection on the name "Internet Security
Systems" due to its general use in a variety of security-related applications.
While we have in the past taken and will continue to take action against any use
of that name in a manner that may create confusion for our products in our
current or future markets, we may not be successful in these efforts.

WE FACE POTENTIAL PRODUCT LIABILITY EXPOSURE AND PRODUCT DEFECTS



                                      -20-
<PAGE>   6

Many organizations use our products for critical functions of monitoring and
enhancing network security. As a result, we risk product liability and related
claims for our products if they do not adequately perform this function. In our
licensing agreements, we typically seek to limit our liability for special,
consequential or incidental damages, but these provisions may not in all cases
be enforceable under applicable laws. In addition, we currently have $2.0
million of product liability insurance coverage that, subject to customary
exclusions, covers claims resulting from failure of our products or services to
perform their intended function or to serve their intended purpose. A product
liability claim, to the extent not covered by our insurance, could materially
and adversely affect our business, operating results and financial condition.

Complex software products such as ours may contain undetected "bugs" that,
despite our testing, are discovered only after installation and use by our
customers. The occurrence of these bugs could result in adverse publicity, loss
of or delay in market acceptance or claims by customers against us, any of which
could have a material adverse effect upon our business, operating results and
financial condition. Customers who deploy or use our products improperly or
incompletely may experience temporary disruptions to their computer networking
systems, which could damage our relationship with them and our reputation. Our
current products may not be error-free and it is extremely doubtful that our
future products will be error-free. Furthermore, computers are manufactured in a
variety of different configurations with different operating systems (such as
Windows, Unix, Macintosh and OS/2) and embedded software. As a result, it is
very difficult to comprehensively test our software products for programming or
compatibility errors. Errors in the performance of our products, whether due to
our design or their compatibility with products of other companies, could hinder
the acceptance of our products.
