Network security – and network penetration testing by extension – evolves as quickly as the technology it’s built on. For penetration testing services that go beyond a simple vulnerability scanner, you need experts in the industry.
Rhino Security Labs’ approach to network pentesting goes above and beyond standard vulnerability analysis. With decades of combined security experience, our assessment team identifies, exploits, and documents even the most subtle of network vulnerabilities. When you’re concerned about your network security, you want the top pentesting company to review it.
A network penetration test provides your organization with a unique birds-eye view of your security system’s effectiveness. Newer companies may not yet have a handle on their network security. Conversely, more mature companies often have large, multi-faceted networks that easily overlooked elements—particularly as more organizations move to cloud-based systems. Both of these scenarios leave the potential for catastrophic breaches.
In either case, you will be made aware of security flaws before attackers can exploit them. With this powerful foresight, business leaders will feel prepared to make informed decisions about their enterprise’s security. In demonstrating your newly hardened security posture, your clients, partners, and investors will feel confident in your ability to protect their assets, as well.
The trouble with using automated scanners is best described with the words of Mark Twain: “Knowledge without experience is just information.” Very often, these scanners miss subtle security risks — it takes an experienced individual to understand the application context and how logic could be abused. Many vulnerabilities simply are not found in these automated vulnerability scanners.
Rhino Security Labs’ expert security engineers often employ the help of vulnerability scanners in the preliminary stages of an assessment, though it is only the beginning. With a more granular understanding of the application and its context, we can provide assessments that are more relevant to your clientele and individual security needs.
Your perimeter network is attacked every day and even small external vulnerabilities can be damaging. External network penetration testing identifies vulnerabilities on infrastructure devices and servers accessible from the internet.
External penetration testing assesses the security posture of the routers, firewalls, Intrusion Detection Systems (IDS) and other security appliances which filter malicious traffic from the internet.
Rhino’s security engineers approach the local area network as an attacker on the inside. We look for privileged company information and other sensitive asset s. This involves incorporating a variety of tools, uncovering user credentials, and attempting to compromise both virtual and physical machines present in the network environment.
The benefit of this engagement is in ensuring a breach of your external network will not result in a breach of your assets.
Wireless (WiFi) networks may be susceptible to a myriad of attacks, depending on the wireless clients, access points, and wireless configurations. New exploitations against WiFi networks are being developed every day, such as the recent KRACK vulnerability which allowed malicious actors to break the encryption protocol between most routers and connected devices.
Wifi is a hotly pursued target, as a compromise of the wireless network is generally the fastest means to the internal network. Poor configuration and weak protections could leave your internal information exposed to anyone in range with a laptop or smartphone. As such, Rhino tests the range of the network in addition to the range of potential vulnerabilities. This includes testing for ‘Wireless Bleeding,’ where we identify the distance at which a potential attacker can pick up your wireless signal.

Rhino Security Labs excels at operating under a structured, repeatable methodology. We stress this concept in every engagement to ensure our findings are reliable, reproduceable, and of excellent quality. As such, our vulnerability assessments can always be verified by your team, both before and after remediation. To get these results, we adhere to the following steps:
1 – Scope
Effective communication with the client organization is emphasized here to create an operating environment comfortable to both parties. During this phase, we accomplish all of the following:
Combining many Open Source Intelligence (OSINT) gathering techniques, This data includes employee positions, social media profiles, cached/leaked information from Google, and more. All of this will help us to understand the innter-workings of the organization, which will aid us in exploitation and accurately assessing risk later in the engagement.
3 – Enumeration and Vulnerability Scanning
In this phase, we utilize a variety of automated tools and scripts among other methods of advanced information gathering. We also take the time to closely examine all possible attack vectors. In the next stage, this gathering and planning will be the basis for our exploitation attempts.
4 – Attack and Penetration
After careful preparation, focus turns to exploiting the discovered network vulnerabilities. Rhino engineers begin working to prove the existence of conceptual attack vectors while preserving the integrity of the network. At this point in the engagement, we begin the following tasks:
5 – Reporting and Documentation
Reporting is critical to the success of the assessment, as it provides the lasting documentation to share with management and vendors. Each report is customized to the specific scope of the assessment and risk based on the individual organization. The reports are intuitive to read, but thorough in the findings. In addition, each vulnerability includes a detailed remediation strategy. Some of the elements that you will find in our reports include:

6 – (Optional) Remediation Testing
As an additional service, Rhino Security Labs will revisit an assessment after an organization has had some time to patch vulnerabilities. We will retrace our steps from the engagement to ensure changes were implemented properly. Our engineers will also search for new vulnerabilities associated with the updates, such as misconfigurations in the network or flaws in a new software implementation. At this point, we will update our previous assessment to reflect the new state of the system.
