2. CREATING CERTAINTY Sertus are a software vendor who specialise in developing pre and post network change tools for the IT environment. Sertus is a post-change assurance tool used to assist organisations with: - Pre and post network device configuration change verification. - Problem identification, isolation and historical review. Sertus evaluates the impact of pending configuration changes faster than any other tool and helps the network engineer mitigate service outage risks due to network change and device mis-configuration. It generates ‘pictures’ of network device status, analyses and compares state, executes change commands to single/multiple network devices. The Sertus tool is easy to integrate and simple to use within existing operational environments. Sertus can operate as standalone PC-based or local server based or integrated with existing management platforms such as Solarwinds, Ciscoworks, HP Openview and Tivoli. 2COPYRIGHT © 2010 SERTUS NETWORKS LIMITED - ALL RIGHTS RESERVED Who are/what is Sertus?

3. CREATING CERTAINTY If are any of these apply to you: Under pressure to reduce operational costs and improve change engineer productivity? Facing the challenge of managing growth in network change volumes within the current network change window and/or constrained operational budgets? Being requested to contribute to quicker time-to-market lead times re network change performance, to enable faster revenue turn-up and release of new products and services? Looking to improve network change quality and mitigate customer service outages related to network change activities? Struggling to verify the validity and accuracy of complex and/or large network config change files or duplicate changes to multiple devices? Under compliance scrutiny for risk and impact control of network changes and looking for a robust solution? Grappling with skill shortages and inefficient technical escalations?....then work smarter by using Sertus 3COPYRIGHT © 2010 SERTUS NETWORKS LIMITED - ALL RIGHTS RESERVED Why consider using Sertus?

4. CREATING CERTAINTY Improved Engineer efficiency: Up to 500% reduction in the time required to augment a network change, test it’s validity, detect errors and rectify. - Reducing network change activities from hours to minutes. Better protection and risk mitigation of Severity 1 customer outages and potential SLA penalty payments. - Service outages can impact annual revenues by up to 4% (source Aberdeen Group 2008) Greater throughput of scheduled network change events for a given change window period and fixed level of change engineer resource. Improved operational config visibility and incident understanding of ’before and after’ outage investigations. - Contributing to drastically reduced time to fix times and improvement of MTTR. Effective problem identification and resolution: Detailed Sertus test output files can easily be compressed and shared with internal escalation teams and/or external vendor TAC/CoE groups. 4COPYRIGHT © 2010 SERTUS NETWORKS LIMITED - ALL RIGHTS RESERVED Key business benefits from using the Sertus tool

5. CREATING CERTAINTY Sertus is an intelligent router/switch output comparison change tool. Traditional network change processes can take up to 8 hours per change: Sertus intelligent comparator and filtering reduces post change check times to around typically 20 minutes or less: Overall change now only takes 1 hour! 5COPYRIGHT © 2010 SERTUS NETWORKS LIMITED - ALL RIGHTS RESERVED How does SERTUS 2.5 work - 1 Engineer runs commands on the router to capture router state Engineer captures all command outputs and stores them in a text file to compare against files after the change is completed Pre- Network Change (15mins) Engineer carries out network change At this stage, engineer may carry out checks to confirm that the changes they wanted to make have been applied successfully Network Change (20 mins.) The engineer now runs the same commands as the pre- change and stores the results Now the engineer makes an attempt to try and compare the pre and post files Post-Network Change (2~8 hours )

6. CREATING CERTAINTY Sertus can carry out comparisons between the outputs of different router vendors using the same common interface: Sertus Interpreter currently takes outputs for Cisco, Juniper and Open Source BSD/Zebra/Quagga. Other vendor command line interfaces can be developed on request. 6COPYRIGHT © 2010 SERTUS NETWORKS LIMITED - ALL RIGHTS RESERVED How does sertus work - 2 Engineer uses Sertus Scripter to get the data from the network devices Retrieved data is parsed (Sertus Interpreter) and analysed (Sertus Comparer) Analysed data is presented to engineer

7. CREATING CERTAINTY 7COPYRIGHT © 2010 SERTUS NETWORKS LIMITED - ALL RIGHTS RESERVED How does sertus work - 3 Command line set examples: Show ip xx Show ip bgp xx Show ip ospf xx Show Multicast xx Show Switch xx Show Open BSD xx Scripting commands Junos commands Filtering of gathered device output data, for example: Show all config changes Show only routes with next hop changes. Identify mission critical routes and flag only missing routes, post the change. etc

8. CREATING CERTAINTY 8COPYRIGHT © 2010 SERTUS NETWORKS LIMITED - ALL RIGHTS RESERVED How does sertus work - 4 Sertus: Is non-intrusive to the network to access device information. Does not use SNMP or device traps to collect device config information. Uses normal device command line interface syntax to gather data and run scripts.
