information Security and IT Manager at Discover Dollar Technologies Pvt Ltd.
It is very resource-intensive, consuming a lot of memory and CPU.
Security Specialist at Prudential Systems Japan
If Microsoft experiences downtime, this solution goes down as it is a SaaS-based solution where we have no control.
Cloud Security Engineer at a computer software company with 51-200 employees
 

Room For Improvement

Acunetix needs improvements in speed, accuracy, usability, integration, and support to enhance functionality and user satisfaction.
Microsoft Defender Vulnerability Management needs simplified configuration, better integration, faster updates, and advanced features for improved security and efficiency.
The main concern is related to false positives; Acunetix needs to work on identifying valid and invalid findings.
Lead Cybersecurity at TBO
I could supply it with maybe a Swagger file or a JSON file, and Acunetix would pick it up, scan all the endpoints according to the OWASP Top Ten, and give me remediation and actionable remediation reports.
Team Lead, Application Security at a financial services firm with 5,001-10,000 employees
Acunetix should have better integration with newer tools such as GitHub and Azure DevOps.
CEO at Xcelliti
This scoring should be for specific industries as well. If I belong to the healthcare industry using Microsoft Defender Vulnerability Management, it should provide me with a risk score and show how I fare against the risk score of my industry.
DGM. Technical Security at a tech services company with 10,001+ employees
A vulnerability I patch within 15 minutes takes 24 additional hours for an update.
information Security and IT Manager at Discover Dollar Technologies Pvt Ltd.
The product is not stable; it often uses excessive memory and CPU, which makes it slow.
Security Specialist at Prudential Systems Japan
 

Setup Cost

Acunetix pricing is seen as high and complex, impacting renewal decisions due to cost transparency and fluctuation issues.
Microsoft Defender Vulnerability Management offers competitive pricing in industry, though costs can be complex, especially for non-partners.
The pricing cost is affordable for small and mid-sized organizations, and when compared to Checkmarx, it is significantly affordable, as Checkmarx is quite expensive.
Lead Cybersecurity at TBO
We secured a special licensing model for penetration testing companies, which is cost-effective.
Information Security Engineer at Tübitak Bilgem
The pricing of Acunetix is pretty expensive and could be improved.
Senior Business Development Manager at Intouch World
Overall, every organization wishes for cheaper options, but we look at the security side as well, so we are good for now.
Senior Cloud Security Consultant at MetLife
For non-partners, however, the cost could be seen as higher, between seven to ten.
COO at Floating-Dot Technology LTD
The pricing is reasonable, and it's included in the whole Microsoft E5 bundle, so it's all-inclusive.
Corporate Planner at MISC Berhad

Rahul Kumar - PeerSpot reviewer
Senior Engineer - Penetration Tester at a government with 10,001+ employees
Identifies vulnerabilities across bulk web applications but needs better support and cleaner reports
The best feature Acunetix offers is the centralized dashboard and the quality of reports it generates, which includes various options for selecting reports and developer options for directly sharing the reports with developers. The centralized dashboard of Acunetix gives visibility into the security aspects of mass applications; for instance, with more than 200 applications, it provides a valuable overview of findings and necessary fixes, along with a high-level summary that helps us achieve compliance through monthly and sometimes weekly scanning. In terms of reporting, Acunetix is excellent because it can generate different types of reports, such as an executive summary report, detailed reports, and developer reports that can be shared directly with developers. Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and OWASP. Acunetix provides a centralized report with compliance-related aspects and a vulnerability timeline, effectively helping reduce vulnerabilities and save time.
OB
Microsoft Solutions Manager at Self-Employed
Ensures strong threat and vulnerability management with continuous risk assessment
The major priority is identity, which is crucial; we have lots of companies in manufacturing, energy, or various sectors, and it varies from one to another. I assess Microsoft Defender Vulnerability Management as very effective in continuously assessing vulnerabilities without requiring scans. We use automatic investigation and remediation features, safe attachments, safe links, and real-time reports, which are also very effective. For Active Directory, Defender has threat intelligence, and we are using that. The risk-based prioritization within Vulnerability Management affects my ability to manage vulnerabilities, particularly in relation to the Zero Trust Model utilized by our customers. The end-users often do as they please in their systems.
