Securing the small business
In recent years the volume of attacks against small businesses has surpassed that of enterprise organizations. However, small businesses do not have the IT staff resources or budgets of larger organizations.
Modern advances in security technology offer small businesses the opportunity to deliver enterprise-class protection within small business budgets.
Small businesses need a workable plan to
provide comprehensive security against today’s
sophisticated threats without spending too

Challenge: Outdated security
Today’s emerging threats are blended attacks that use different techniques to bypass the outdated
stateful packet inspection technology offered by other vendors.
Solution: Unified Threat Management (UTM)
Unified Threat Management (UTM) solutions provide a higher level of protection by scanning traffic for the latest threats including vulnerabilities and malware. By scanning more traffic, UTM solutions reduce the chance of machines on the network from receiving a virus or malware infection. Regular signature updates allow the UTM solution to stay ahead of the latest threats.

Challenge: Provide the best available protection
Knowing the UTM solution you purchased provides the highest level of protection without limiting file sizes and concurrent files downloaded that can be scanned.
Solution: Reassembly-Free Deep Packet Inspection (RFDPI)
Dell™ SonicWALL™ UTM solutions based on patented*
RFDPI technology provide the ability to scan not only standard communications protocols like SMTP, FTP and HTTP, but also many protocols that are stream-based or run over non-standard ports. Additionally, UTM solutions should not be limited by the size or number of files that can be scanned concurrently.
RFDPI: Not all UTMs provide the same level of protection

Challenge: Cumbersome implementation and administration
Small business network administrators often try to combat different emerging threats by cobbling together separate point solutions, which leaves gaps in protection and introduce additional cost and complexity. In addition, because traditional UTM solutions are based on original equipment manufacturer (OEM) technologies, they can require complex policy creation to deploy. This complexity can increase deployment time and lead to a
less-secure UTM deployment.
Solution: Ease of use and management
Small businesses have the opportunity to optimize productivity and minimize total cost of ownership (TCO), while maximizing security, by consolidating multiple security technologies in a single UTM solution. Also, UTM solutions should provide a simple-to-use cohesive management interface that allows quick and accurate UTM policy deployment helping to decrease deployment mistakes, and increasing the UTM security.
Challenge: Incomplete and complex anti-spam protection
Most UTM solutions that provide anti-spam
functionality rely on real-time blacklists (RBLs) and other less-accurate methods for blocking spam. Additionally, some solutions require the administrator to set up a server to run third-party software to provide additional spam blocking options.
Solution: Comprehensive anti-spam
A comprehensive anti-spam service on the firewall should remove spam, phishing and virus-laden messages from inbound SMTP-based email before they reach the network. The hybrid-cloud design of this service simplifies the set-up while optimizing protection, with no need to redirect mail exchanger (MX) records or send email to another vendor to be “cleaned.”

Challenge: Lost Internet connectivity
Most small businesses rely on their Internet
connection to run their daily business, and connect their business locations, partners and customers over a wide area network (WAN). Service interruptions lead to downtime and decrease business
productivity.
Solution: 3G/4G failover
UTM solutions should provide a method of WAN redundancy that includes WAN Failover and Load Balancing. For additional redundancy, administrators can take advantage of today’s 3G/4G cellular
technology by adding a USB-based 3G/4G adapter, allowing the UTM appliance the ability to seamlessly fail over to the wireless network.
Challenge: Network growth management
As business grows, customers are looking for an easy way to segment systems on the network and provide policy enforcement.
Solution: Contextual port interfaces
UTM solutions can provide administrators with an easy method for network segmentation on the UTM appliance to easily control access.

Challenge: The increasing move to wireless
While most companies rely on wired networks, many are now purchasing devices that provide 802.11n technology.
Solution: Clean wireless networks—as secure as wired networks
“Clean wireless” delivers the innovative dual
protection of high-speed secure wireless combined with high-performance UTM. By integrating
802.11n-compatable wireless access points with UTM firewalls, clean wireless can support and enforce one set of security policies over the entire network.

Remote access solutions
Challenge: The rise of teleworkingToday, your office is where you are: at home, at the airport, at a café. Customers, partners and contractors need access to your business from anywhere. In addition, uncertainties ranging from natural disasters, pandemics and terrorism can disrupt access to corporate offices. As more users continue to work from home, it’s more important than ever to allow these users access to internal network resources.
Solution: Clean VPN
VPN offers secure remote access to mission-critical resources from virtually any endpoint, including desktops, laptops, tablets and smartphones. Clean VPN enables administrators to scan and secure the integrity of both inbound and outbound VPN traffic.
