Of particular note, more than two-thirds (69%) of respondents stated that they expect the number of requests to capture network data (including metadata and packet-level data) to increase dramatically, driven by the needs of a variety of IT groups including network architecture, security, compliance, applications, and IT audit teams.
The survey polled 150 IT professionals from various industries, all from enterprises with 1,000 or more employees.
Key findings from the survey include:
- Network performance challenges are increasing, and result from the size, complexity and mobility of modern network environments. The number one indicated network performance challenge (43%) that respondents face is monitoring/managing network performance between groups of web, application, and database servers in the data centre. The second most cited challenge by respondents is maintaining end-to-end network performance to endpoint devices connecting either via public networks (42%) or wide area networks (WAN) (35%). These challenges reflect a rapidly changing environment marked by centralised data centres and an increasingly mobile workforce, which requires extending the boundary of end-to-end management to mobile devices. Other challenges include tuning the network (33%), providing Quality of Service (QoS) based on traffic or application (27%), and understanding network latency (27%).
- Security challenges are increased when there is a lack of proper network visibility for incident detection and resolution. The most often cited challenges from respondents include the struggle to capture network behaviour for incident detection (38%), monitoring network flows for anomalous behaviour (35%), the ability to capture and analyse logs from network and security devices (29%), and the ability to establish a baseline of normal network behaviour (27%).
- Organisations struggle with multiple network monitoring tools to capture network traffic and only see that number increasing in 2014. More than two-thirds (69%) of respondents stated that they expect the number of requests to capture network data (including metadata and packet-level data) to increase dramatically. Requests to capture network data are also now being initiated by the network architecture, security, compliance, and IT audit and application teams.
- More than half of organisations’ monitoring tools cannot cope with increased 10GbE network throughput. 54% of organisations find that they either sometimes or frequently cannot cope with the increased throughput or are dropping packets due to the increased throughput.
