Each MSSP pitch seems to have its own set of three logos. CREST on one side, ISO 27001 right in the middle, SOC 2 on the other side, towards the bottom. Everyone sees them, feels good about it, and moves straight on to discussing price.
But it is a dangerous approach that could prove very costly for you. Data breaches in India cost about ₹22 crore each time. Many of them happen via vendors, not the main entrance point.
So let’s slow down and look at CREST vs ISO 27001 vs SOC 2 properly. They don’t measure the same thing. And once you see what each one leaves out, you’ll read MSSP proposals very differently.
Think about what an MSSP actually gets when you sign. Your logs. Your alerts. Often, admin access to systems you’d never hand to a stranger. If their security is weak, yours is too. It’s that simple.
And vendors are now a favourite way in for attackers. The Verizon 2025 Data Breach Investigations Report found third parties were involved in 30% of breaches, double the year before. Worse, the average breach took 241 days to find and contain.Â
That’s eight months of someone quietly sitting in your network.
Then there’s the law. India’s DPDP Act, 2023 allows penalties of up to ₹250 crore for failing to protect personal data. The regulator won’t care that your vendor slipped up. You’ll be the one answering.
This is why MSSP security certifications matter. They’re independent proof, not marketing claims. You just need to know which question each one answers.
CREST is a not-for-profit organisation founded in the UK in 2006. Currently, CREST accredits security providers and certifies individual testers in Europe, the Americas, Asia-Pacific, and the Middle East.
The examinations are practical in nature, ranging from penetration testing, SOC operations, threat intelligence and incident handling. Being CREST certified means that those doing the job have been proven to be capable of discovering vulnerabilities and handling a real attack.
One thing CREST doesn’t give is the ability of the provider to secure their systems or data. Another problem is that some organisations may only have one certified individual and not even the entire organisation. You should first check with the provider using the CREST member directory.
The most famous security standard is ISO/IEC 27001. It requires an enterprise to implement an ISMS, which stands for Information Security Management System. This is a live process of risk identification and control implementation.
For an ISO 27001 MSSP, having a certificate proves that security here is not on someone’s watch. There are documented procedures concerning access, suppliers, incidents, and recovery. The audit by an accredited organisation is done each year, and there is recertification every three years.
There are two things you can check yourselves. The first one is the scope of the certification. Some companies get the head office certified, while they do not care about the SOC that you pay for. Another thing to pay attention to is the version of the certificate. The 2013 version expired on 31 October 2025 (ISO).
SOC 2 comes from the AICPA, and it works differently from the other two. You don’t get a certificate. You get a report written by an independent CPA firm that has tested the provider’s controls.
With a SOC 2 MSSP, the type of report changes everything. Type I only looks at whether controls are designed sensibly on one day. Type II checks whether they actually worked across six to twelve months. If you only ask for one thing, ask for Type II.
The best part of a Type II report is the exceptions section, where the auditor writes down what went wrong. You’ll learn more from that page than from any sales call. US clients ask for these reports all the time, which is why more than one Cyber Security Company in India now goes through the audit.
There’s no universal winner here. It comes down to which Cyber Security Services you’re buying and who your own customers are.
Buying penetration testing or incident response? CREST should weigh heaviest, because skill decides how those engagements go. If you’re in banking, insurance, healthcare or another regulated sector in India, ISO 27001 is pretty much the starting point. Auditors expect it.
Selling to the US? Add a SOC 2 Type II report to your list, because your clients will ask about your vendors sooner or later. And if the MSSP is going to run your 24×7 monitoring, I’d want to see all three. At that point, you’re trusting them with nearly everything.
Certificates are the entry ticket. The real MSSP evaluation starts when you ask questions like these and watch how the provider responds:
Don’t skip that last one. The world is short of about 4.8 million security professionals, and plenty of SOCs are running thin. A good provider will answer without flinching. A weak one will change the subject.
In the CREST vs ISO 27001 vs SOC 2 debate, CREST shows a team can do the work. ISO 27001 shows the company is run with discipline. SOC 2 shows the controls held up when nobody was watching. You want a provider that can prove all of that.
So don’t stop at the logos. Ask for the scope, read the report, and check the directory yourself. With breaches in India costing more than ever, the wrong partner can wipe out crores and years of trust.
At ECS, our Cyber Security Services are built for it. As a best Cyber Security Company in India, we maintain proper transparency. Reach out to the ECS team and ask us the hard questions.
Neither is better on its own. ISO 27001 shows a managed security system. A SOC 2 Type II report shows that the system actually worked over time. Most serious buyers want both.
No, there’s no legal requirement. Still, if you work with US clients, expect them to ask for it.
Search the CREST directory, ask for the ISO 27001 certificate along with its scope, and request the SOC 2 Type II report under NDA.
