Offensive Security Consultant

performance is pretty poor, licensing experience is poor, does not normalize scope data, does not always show its work in scan output, lots of typos in finding text, filtering does not work as well as one would hope

Vulnerability Assessor

Accuracy of scans are good and detects most vulnerabilities like SQL injection, XSS, and other misconfigurations.

Responsable On-Premise and Cloud Infrastructure

Nessus allows you to have vulnerability dashboards and allows rapid remediation

Automated scans are very friendly to setup and compares scope to OWASP top 10 vulnerabilities.

Solid product, minus reporting. But massively overpriced and undermaintained.

Associate Professor

Together with Nmap, Nessus gives a much better penetration testing and vulnerability analysis of networks and virtualized cloud infrastructures.

Systems Engineer

Sometimes there are limitations in the scan exclusions.

Sometimes the vulnerability scan is a little too picky.

Lead Security Consultant

User Interface , Scan Profiling , Policy creation is easy and straightforward

Lead Consultant

Price can be a bit steep for small businesses

nessus is complicated to configure but also is a fairly expensive product

Nessus is a must for network security testing and vulnerability analysis.

Owner

I use Nessus for external vulnerabilities.

IT Intern

Data analyst 

Nessus still has the issue of false positives which is common in most vulnerability scanners whereby nessus detects vulnerabilities that are not present.

Analyst

Nessus proved to be an effective solution for identifying potential security weaknesses and ensuring compliance across our infrastructure.

Senior Software Security Analyst

Also, many false positives can be encountered and then depends on the analyst to interpret and classify each vulnerability along with a more appropriate severity.

Lead security Engineer

One of the best features is nessus can be easily deployed to air gapped environments without much changes to the environment.

System Admin

Nessus is the state of the art on automating vulnerability scans for networks and infrastructure.

At times the most recent CIS benchmarks may not be available to conduct compliance scans.

I also like the wide variety of plug ins made available by nessus for specific vulnerabilities.

Network Security Engineer

I wish there was a way to combine data from multiple scanners into one report or view.

Cyber Securit Analyst

Perfect tool for consultants as you can load it on a laptop and move from client to client.

Nessus has limited reporting and vulnerability management features as compared to other tools.

I like how you get an alert promptly when nessus detects an attack on any of your systems.

Manager

Nessus is #1 Vulnerability scanning tool which I ever seen and also Nessus tool has given  fullest support to get PCIDSS certificate to our organization.

CISO

Tenable kept removing core functionsWeak web scanning capabilities

Reporting is a little lacking and can do with some rework.

It can be expensive to keep it running for smaller business.

The "Plugin Output" fields help greatly when trying to determine if tests are a false positive, and lends additional credence to your system administrators when you can show them exactly *why* something has been detected as a vulnerability.

Nessus is easy to use and easy to deploy vulnerability assessment solution available.

Information Security Analyst

Nessus is one of the best vulnerability scanning tools in the Cyber Security field.

IT Specialist (INFOSEC)

Also, sometimes scans fail with very little information as to why.

Cybersecurity Masters Student and Teaching Assistant

False Positives are present, and its not your only tool to rely for a pentest.

As an overall comment, Nessus is very good to manage your infrastructure assets from cyber attacks.

There are no ways to track vulnerabilities or your efforts to monitor them over time; this truly is just a point-in-time view of your environment unless you upgrade to a much more expensive product.  

So if you are expecting to work like any other web app OWASP scanner, its not.

As per my 2+ years of experience with the Nessus tool, sometimes it contains false-positive results.  

Nessus is still the industry leader in this arena, and the ability for the product to identify vulnerabilities accurately is still the high water mark to beat.  

It is better if nessus professional have option to track an assets progress over the time with vulnerability management features.

Director Of Information Technology

Provides a good overview of vulnerabilities across systems for internal security assessments and audits.

It is relatively easy to use once everything is set up, and it can scan just about anything.

Assistant Manager - IT Network and Operations

When it comes to compliance, Nessus really plays  major roll.

Doctoral Student

For threats that are generally manageable and can easily be detected, Nessus is the to go-to scanner of choice

Orca Security

Web-based

Trend Micro Deep Security

Digital Marketing Specialist

The tool has helped us back up corporate data from various platforms, protecting against data loss and storing it securely in the cloud.

Orca has been able to let us just set things to "automatic" and it just works.

The technical and commercial support is also excellent.

Manager - Information Security Operations

The team is always available when we have issues and is able to resolve anything we see quickly.

Information Security Manager

Easy integration and automation, very quick time to value, aggregation of alerts, automatic prioritisation, recognition of alternative mitigations, mapped attack paths, responsive support and product development.

Another reason I like Orca is the support I have gotten.

Integration of Orca Security with Microsoft Teams to provide realtime alerts when issues are detected is in it's infancy at present, and we had some troubles getting it going.

Senior SOC Analyst

Orca allows collaboration across departments to manage cloud compliance, security, and posture.

Senior Application Security Engineer

The recently introduced attack paths feature shows graphically how an attacker could gain access and potentially pivot through the system.

Product Security Engineer

Single pane of glass visibility into your Cloud infrastructure with a powerful query language and automation features.

Senior Security Engineer

Orca helps us maintain and improve our cloud security by prioritizing and contextualizing findings

Senior Vuln Mgmt Lead

Ontop of being a great product, their support has been outstanding in answering all of our questions, fixing bugs, and expediting our open cases.

Automated scanning for the log4j vulnerabilities were available within a couple of days of disclosure.

The only dislikes of Orca that I have emphasized to their support team is around vulnerability management reporting and navigation within the tool.

DevOps Engineer

It is a reach platform which provides us with comprehensive security tooling features.

Security Analyst

Easy integration, ease of understanding of risks and detailed information and categorization of risks in our environment

DevSecOps Engineer

I loved working with Orca Security as vendor!
