Our Approach

At CISI – Covert Intelligence Surveillance & Investigation, we are known for being highly selective private investigators in Mumbai, India. We don’t believe in volume-based operations. Instead, we focus on delivering high-quality, confidential investigation services with precision, integrity, and ethical commitment.

As a reputed private detective agency in India, we accept no more than 8–10 investigation cases per year. Looking at the past 10 years data, we’ve taken up only 86 cases selectively, and successfully solving 83% of them — a track record that reflects our focus on real results, not false promises.

Due to the resource-intensive nature of our operations, our services are reserved for elite clients across Mumbai, Delhi, Bangalore, Hyderabad, and other metro cities, facing genuine, high-stakes situations. Every inquiry is evaluated through a strict screening process to ensure the client’s intentions are legal, ethical, and aligned with our values.

If your case doesn’t meet our criteria, we may respectfully decline the request.

At CISI, confidentiality, trust, and truth aren’t optional — they are our foundation.

Founder & CEO

CISI Founder - Mr. A. Kumar

Mr. A. Kumar (alas AK) is the Founder and CEO of Covert Intelligence Surveillance & Investigation, one of the most trusted and result-driven private investigation agencies in Mumbai and pan India.

Born and raised in India, Mr. Kumar's passion for spy movies, detective novels, and surveillance gadgets shaped his early dream of becoming a professional private investigator. In 2003, at just 22, he began his career as a field investigator with a well-known detective agency in Delhi, gaining firsthand experience in undercover operations and intelligence gathering.

In 2008, he moved to Mumbai and launched his own independent agency — today known as CISI, a name synonymous with confidentiality, accuracy, and elite client service. Over the past 20+ years, Mr. Kumar has led hundreds of sensitive and high-stakes investigations across major metro cities including Delhi, Bangalore, Hyderabad, Kolkata, and more.

With an unwavering commitment to ethics and client satisfaction, Mr. Kumar often says:
“Work as per the client’s satisfaction. Fee as per our satisfaction. No compromise in that.”

By 2030, he plans to expand CISI – Covert Intelligence Surveillance & Investigation internationally, offering world-class investigation services to clients across borders.

Spy Phone Software

Spy Phone Software

Your mobile phone is your most personal device — it holds your messages, memories, calls, passwords, and locations. It knows everything about your life. But what if that privacy is compromised?

With the rise of advanced spy software and mobile hacking tools, your phone can be accessed remotely — without your knowledge. In today's digital age, especially for Android users, the threat is real. Spy software can silently monitor your calls, WhatsApp chats, SMS, browsing history, live location, gallery, camera, microphone, and much more — all without physical access.

At CISI, we can help you in two areas:

-> Spy phone software for ethical use (parental control, employee tracking on company devices)

-> Mobile spyware detection services (if you suspect someone is spying on your phone)

We provide spy software for Android, iPhone, laptops, and PCs — strictly after verifying the legitimacy and intent of the user. Misuse is a punishable offense.

If you're concerned about your child’s safety, suspect a cheating partner, or want to monitor your own company devices, our spy phone software solutions in Mumbai can help you sleep peacefully at night.

We also offer "Spyware Detection Service" — just share your device’s IMEI number to check if you doubt that your mobile has been hacked.

⚠️ Legal Note: Never install any mobile monitoring software on a phone you don’t own or without the user’s consent. Doing so is illegal and may lead to criminal charges.

With over 20+ years of experience in private surveillance and cyber intelligence, CISI has become a trusted name in spy mobile phone and PC software services in Mumbai and across other metro cities like Delhi, Bangalore, Hyderabad, and Kolkata. Our tools are used ethically by concerned parents, business owners, and individuals who seek truth, safety, and control over their digital environment.

Unfortunately, many free or pirated spy apps available online are unsafe, unverified, and illegal. These can expose your own device to tracking, malware, or data theft. That’s why our team ensures every client is vetted, and every use case is verified before software is provided.

We also educate clients on mobile security best practices — like using strong passwords, avoiding public Wi-Fi, regularly updating operating systems, and managing app permissions cautiously.

If you need expert help in detecting mobile spyware or installing legitimate spy monitoring software, CISI is your trusted intelligence partner in India.

Spy Gadgets

Spy Camera and Gadgets

In today’s digital age, hidden cameras and spy gadgets are everywhere — in public places, offices, cars, hotel rooms, and sometimes even inside your own home. Since the invention of the first hidden spy camera by Robert D. Gray in 1885, the privacy of individuals, especially celebrities and high-profile personalities, has been at constant risk.

These cameras can be cleverly disguised in everyday objects — lighters, books, electrical sockets, clocks, bulbs, or even pens and wristwatches. Without expert tools, it’s nearly impossible to detect these devices with the naked eye.

At CISI, we provide both spy camera detection services and sales of high-grade spy gadgets in Mumbai, Delhi, Bangalore, and other metro cities. Our inventory includes:

Wireless hidden cameras
Pen cameras
Button and clock cameras
Miniature trackers
Audio bugs
Custom-designed spy cameras (as per your requirement)

We also offer anti-spy devices such as:

Spy camera detectors
Audio bug scanners
RF signal scanners

All our spy gadgets are industry-grade Korean products, trusted for professional use. Whether you're looking to secure your privacy or monitor a suspicious environment, CISI has the right tools and expertise.

If you suspect you're being watched, or need high-quality spy equipment, contact us today for a discreet consultation or place your order via call/email.

All our spy equipment is tested and recommended for lawful personal use, corporate monitoring, child safety, or evidence collection in serious cases. Whether you're dealing with marital infidelity, employee misconduct, or personal safety concerns, our tools can help you gain the proof you need without raising suspicion.

We do not sell or recommend spy gadgets for any illegal or unethical use. Every buyer is required to submit a valid identity proof and confirm their intentions comply with legal guidelines. We believe in responsible surveillance — and we ensure that every product we provide is used only for justified, ethical purposes.

Our team also assists clients in custom spy gadget recommendations based on their unique requirements. We deliver across Mumbai, Delhi, Bangalore, Hyderabad, and other major cities in India.

On Session app, we do not entertain random chats showing no payment screenshot.

Why do you charge for an appointment?

Hiring private detective and intelligence services is a high-cost affair, typically accessible only to financially capable individuals. Our appointment fee serves as a filter to ensure that only those who are serious and financially prepared to pursue genuine private investigations approach us.

Though case discussion on whatsapp chat/audio call is free of charge. Scan our whatsapp QR code in "Contact Us" section to initiate a chat with us. We strongly advise you to send a WhatsApp message first instead of calling directly.

What does it mean by “Appointment Validity”?

"Appointment validity" means your paid appointment remains valid either for a specific period or for a specific number of meetings—whichever comes first. All paid appointments are valid for either one meeting or one month from the date of payment, whichever happens earlier.

Once either the one-month period passes or the scheduled meeting is completed, the appointment validity expires.

No office address is given. How can I visit your office?

"Visiting our office is strictly by invitation, only after we have positively decided to take up your case. We value privacy and do not entertain walk-ins. Just for your knowledge, our office is located in the western suburbs of Mumbai."

How can I trust that my personal information and case details will remain confidential?

You're absolutely right—trust is hard to find.

That's why confidentiality isn't just a promise here—it's our strict, non-negotiable policy. We never record, share, or leak any personal or case-related information. Every discussion remains 100% private and protected within our system. See "About Us" section for more detail.

What is your agency's success rate?

Our success rate varies depending on the type of case. In some categories, we have achieved up to 90% success, while in others, the success rate may be below 60%. On average, our success rate is around 78%.

We believe in honest and realistic assessments, as every case presents unique challenges. Success largely depends on the nature and complexity of the case. More on "Our Approach".

In what kind of investigation do you guys have expertise?

We classified all cases into two categories. Personal or professional. We have expertise in problems related to personal life problems like love affairs, post-matrimonial investigations, divorce cases, child monitoring, and physical surveillance.

Read our client testimonials. They are very short because we are very much concerned about our client privacy, but you will get a message.

What if it’s an overseas investigation? Will you do it?

If the whole investigation has to be done outside India, then “No”. But for partial investigation, it’s a “Yes”.

I am worried about my privacy. What’s the solution?

If your intention is right then we have a modern covert way so that your assignment will be done and you have no need to reveal your identity. The first step is to book a “100% Confidential Online Appointment”. In that method, we will never come to know who you are and your contact details.

If, you are afraid of being a victim of “Blackmailing” then that’s your only option to go for a “100% Confidential Online Appointment”. Seeing the nature of business, in the end, you have to trust someone.

Does your agency have a government license or any affiliation?

In India, the government does not issue any license or authorization to private detective or investigation agencies to operate—unlike in countries such as the USA, the UK, and others where licensing systems exist.

The Private Detective Agencies (Regulation) Bill, 2007, which aimed to regulate private detective services in India, was pending in the Rajya Sabha for several years. However, this bill was officially withdrawn from the Rajya Sabha in 2020 following recommendations from the Standing Committee, which suggested certain revisions and updates. As of the end of 2024, the bill has not been reintroduced in either house of Parliament. We will continue to update this section if there are any further developments.

Now that you're aware of the licensing facts, you should know that any detective agency claiming to be “government-affiliated” is misleading you. In reality, there is no such government affiliation for private detective agencies in India. Some agencies form associations or groups and issue certificates among themselves to appear official—but these are not recognized by any government authority, neither us.

How much time do you take for spy camera delivery?

For spy-gadgets, delivery timelines depend on stock availability. Generally, orders are delivered within 5 to 7 working days. Before accepting any payment for a spy gadget, we will inform you of the approx. delivery date in advance.

Which mobile devices are compatible with your spy phone software?

Our spy phone software is compatible with both **Android** and **iPhone** devices.

However, we strongly advise that you install the software only on a device you personally own. Unauthorized installation on someone else’s device may violate privacy laws in many countries and could lead to legal consequences.

Please ensure you comply with local laws before using such software.

I can’t afford much. Will you still take my case?

We understand financial constraints; however, private investigation services involve significant costs due to the expertise, time, and resources required.

If your budget is limited, we may not be the right fit for your case. We advise against hiring low-cost agencies, as they often compromise on quality and effectiveness. In such situations, it may be more practical to explore personal investigation options rather than risking unreliable services.

What is your advance payment policy for assignments?

Our standard advance payment policy is as follows:

General Cases: 25% advance before starting the assignment, 25% during the process, and the remaining balance upon successful completion.
Physical Surveillance: Payment for a minimum of 3 days is required in advance.
Missing Person Cases: 50% advance before commencing the investigation. Balance on successful complition of the case.

In most cases, the initial advance is generally 25%.

What are your accepted payment methods? Do you accept cash?

We accept payments through both **cash** and **bank transfers**.

Once your case is accepted, we will provide you with the necessary payment details and instructions. Appointment payments are accepted only via bank-transfer.

Do you offer refunds?

Due to the nature of our services, once an investigation has begun, refunds are not possible under any circumstances.

However, if you cancel the case before the investigation starts, you are eligible for a full refund—excluding the **appointment fee** and any expenses already incurred (if applicable).

Please note that the appointment fee is strictly non-refundable in all situations.
